How many different cards are there in soccer?

Soccer has two types of cards, yellow and red. Yellow cards are used to caution a player for a major breach of the rules, called "misconduct". A second yellow card, as well as several egregious forms of misconduct, warrant a red card, which indicates that the player is sent off and can no longer play in that game or remain in the vicinity of the pitch.

Some similar games (which do not follow the IFAB Laws of the Game) can employ blue, green, black, white, or even so-called "soft red" cards to mean various things, but they aren't part of the soccer / football that most of the world plays.

A womens father is colorblind She marries a colorblind man Will there son or daughter be colorblind?

Colorblindness is an X-linked recessive disorder. This means girls (who have the sex chromosomes XX) must have a colorblind X from dad and a colorblind X from mom. Boys only need to have one colorblind X to be colorblind because they have sex chromosomes XY (and have only 1 X).

If the dad has it, he has the colorblind X. If the daughter has it, she must have gotten her mom's colorblind X. If the mom is colorblind, then every child they have will be colorblind. If the mom is not colorblind, then she must be a carrier - she must have 1 normal X and 1 colorblind X.

Mom is either colorblind (with 2 colorblind Xs) or she is a carrier. Dad is definitely colorblind.

How many cubic yards are in a sidewalk that's 48in wide by 40ft long by 3.5 in thick?

1 cubic foot = 1,728 cubic inches

1 cubic yard = 27 cubic feet = 46,656 cubic inches

1 ft = 12 inches

40 ft = 480 inches

Volume of the walk = (48" x 480" x 3.5") = 80,640 cubic inches = 1.7284 cubic yard (rounded)

What are all the 4 digit combinations with 0-9?

Method 1: four digit number start after 999 and end at 9999

so 4 digit no. = 9999-999 = 9000

method 2: - - - - there are four places in 4 digit no. In first place only 1-9 can come , for rest 0-10

so total no. = 9*10*10*10=9000

* * * * *

Wrong!

Those are the number of PERMUTATIONS, not combinations. In a combination, the order of digits does not matter. So 1234 is the same as 1342 or 4213 etc.

What is the probable cause of p0441 trouble code in an OBD2 system?

evap emmision system. purge solenoid not operating, or vacuum line broken between engine and charcoal cannister, near gas tank, underside of vehicle. solenoid may also be unplugge damaged, or engine computer could be defective.

On my 02 Intrepid it was the EVAP bleeder filter mounted just behind the fuel tank. I found this solution by checking the vacuum switch mounted on the carbon cannister. An answer I found on the justanswer website. Post copied included below.

Hello inspector 13, The set condition for this trouble code po441 has nothing to do with the oxygen sensor changing voltage when the purge valve opens up.

The Pcm gradually increases purge flow. During flow the PCM looks for the NVLD (natural vacuum leak detection) switch to close. If the PCM does not see the switch close at maxium flow an error is detected.

First pull up the lower cushion for the back seat, there is a wiring connector on the right side. We always check this first because we had a couple vehicle with corroded connections.

The problem we at Chrysler, are finding is the internal switch at the NVLD is not working properly and closing as it should.

This unit is located on the right side of the gas tank, and is part of the charcoal canister.

REMOVAL
1. Disconnect the negative battery cable.
2. Remove fuel tank, refer to the Fuel Delivery section for Fuel Tank Removal.
3. Disconnect the electrical connector from the NVLD assembly.
4. Disconnect the hoses from the NVLD assembly
5. Lift tab on NVLD assembly and twist the assembly counterclockwise and pull up to remove from EVAP canister
6. Remove O-ring from EVAP canister .
