Probability

The answer depends on how many cards you are dealt!

Probability is measure on a scale of 1 to 0

False.

A die has six sides, so the probability of rolling an even number is 1 in 2, or 50-50. A coin has two sides, so the probability of flipping the coin and getting heads is 1 in 2, or 50-50.

The probability that both will happen together is the one in two OF one in two, or one in FOUR chance that both will happen.

So, the probability is 25%.

Recall that probabilty is the quotient of specific outcome divided by all outcomes. This is a relatively small problem to enumerate, so here goes...

1 + 1

2 + 1

3 + 1

4 + 1 = 5

5 + 1

6 + 1

1 + 2

2 + 2

3 + 2 = 5

4 + 2

5 + 2

6 + 2 = 8

1 + 3

2 + 3 = 5

3 + 3

4 + 3

5 + 3 = 8

6 + 3

1 + 4 = 5

2 + 4

3 + 4

4 + 4 = 8

5 + 4

6 + 4

1 + 5

2 + 5

3 + 5 = 8

4 + 5

5 + 5

6 + 5

1 + 6

2 + 6 = 8

3 + 6

4 + 6

5 + 6

6 + 6

You can see that the number of instances of the parent set is 36, while the number pf omstamces of the desired set is 9. As a result the probability of throwing a 5 or 8 with two dice is 9 in 36, or 1 in 4, or 0.25.

For the dataset {26, 30, 34, 38, 42, 46, 50}:

n = 7

Σx = 266

Σx² = 10556

µ = 1/n Σx

σ = √(1/n Σ(x - µ)²) = √(1/n Σx² - (1/n Σx)²)

→ σ = √(1/7 × 10556 - (266/7)²) = √(1508 - 38²) = √64 = 8.

I used the formula SD = sq rt {Sigma[(x - mean)^2]/n} where sigma means the sum of; ^2 means squared.

Firstly, find the mean of the data = 50.

Subtract each term separately from the mean and square it.

Add these 10 terms and it comes to 11424

Divide by the number of terms, 10 = 1142.4

Then find the sq rt = 33.79.

If you toss the die often enough then the probability of getting the sequence 2-2-1 is 1: a certainty. The probability of getting the result in the first three tosses is 1/216.

The probability is 1 and you do not need Matlab to get that answer - only a little bit of thought.

2.026

The probability is X/(X + 2W) where X is the number of orange gumballs.

The answer depends on where in the world the random selection is taken since the location will determine the mix of cars that the selection is made from.

Considering that a this is a six-faced die, the probability or rolling a 5 or 6 is 2/6. Or to simplify it, 1/3. This is because there are six sides, and you want to get two out of the six sides.

These are independent events; neither one depends on the results of the other.

The answer will depend on what numbers are on the wheel, what the variable is (the sum, product or some other function of the individual spins). Since there is no information on these factors, the question cannot be answered.

If you roll them often enough then the probability is 0. For just one roll, the probability is 35/36.

Odds of rolling ONE six - 6:1

Odds of rolling TWO sixes - 36:1

Odds of rolling two sixes, SIX times - 216:1
