The odds against getting a royal flush in poker on first five cards dealt is 649740 to 1 Find the probability of this event?

I will assume you numbers are correct, and the odds of NOT getting a royal flush is 649740 to 1, then the odd of a royal flush is the reciprocal of that. When we speak of odds in probability it has a very specific meaning. If P is the probability of an even , then the odds in favor of P are P/(1-P). For example, the odds of getting a 6 when we throw a die is not 1/6, it is 1/6 divided by 1-(1/6) or 1/6 divided by 5/6 which is 1/5 or 1 in 5. The odds of not getting a 6 is 1/(1/5)=5 to 1 So your given odds are 649740/1 and the odd of getting the royal flush are 1/649740.

How do you find probability from a probability generating function?

you ether use a graph tree diagram or web diagram to answer the possible outcomes of the question possible outcomes meaning the number of outcomes the person will have in the probability or divide the number of favourable outcomes by the number of possible outcomes favorible outcomes meaning the number of outcomes all together

What is the probability of getting a zero for feelings on the Myers-Briggs test?

In order to calculate such probability, you have to know the number of questions in that particular Myers Briggs test that refer to the Thinking/Feeling dichotomy. Assuming that you will pick answers randomly, the probability will be lower when there are more questions. For 8 questions on T/F preference, there is a 12.5% probability for a score of 0 on Feeling. For 16 questions, the probability is 6.2%. For 32 questions, the probability is 3.1%. etc. If you pick your answers according to your own beliefs, it would be very difficult to assess such a probability. However there will be a approx. 30% higher chance for a man to score 0 on Feeling than for a woman.

What is the probablity of drawing a diamond then a red card?

If you flip a coin three times what is the probability of getting 2 heads?

The possible outcomes are:

hhh

hht

hth

thh

htt

tht

tth

ttt

If you mean exactly 2 heads (and not 3 heads), then you can see 3 out of 8 possibilities have exactly 2 heads. So the probability is 3/8 or 0.375

If you mean at least 2 heads (2 or 3 heads), then 4/8 or 0.5.

What type of probability distribution is the normal distribution?

It is a continuous parametric distribution belonging to the family of exponential distributions. It is also symmetric.

How do you find the probability of x is more than 1 if a fair coin is tossed 4 times and x is the PRODUCT of the number of heads times the number of tails?

Suppose the number of Heads is H where H = 0, 1, 2, 3 ,4.

Then the number of Tails is 4-H.

Their product is X = H*(4-H) = 0, 3, 4, 3, 0

Thus X is NOT more than 1 only if H = 0 or H = 4

The probability of each of these events is 2-4 and so their combined probability is 2-3 = 1/8.

Therefore, Prob(X > 1 ) = 1 / 1/8 = 7/8
