In a family of 5 what is the probability that you will have 3 girls (please show your work)?
StephenKiddlefb6186
The probability of a female is approx 0.4831 across the world. If you assume (rather dubious) that the genders of children in a family are independent then the probability is approx 0.3012
In a family of 5, the probability of 3 girls and 2 boys is
5C3*(0.4831)3*(0.5169)2 = 0.3012

Suppose you roll a die 3 times What is the probability that the face 6 will never show up?
The probability that a six will never show up in three rolls of a die is 125 in 216. The probability that a six will not show up in one roll is 5 in 6. Raise that to the third power to get 125 in 216.
What is the probability of flipping 2 coins and having both show heads?
If both tosses are fair, the probability of that outcome is one in four.
What is the probability that exactly 2 coins will show heads?
one fourth
What is the defition of probability?
Probability is the likelihood that the desired outcome would happen in a set situation. Small amounts of tests may show a skewed number differing from the probability but as more simulations are ran the actual result will get closer and closer to the probability.
You roll 2 dice What is the probability that the sum of the dice is prime and both dice show the number 6?
The probability is 0 since if both dice show the number 6, their sum is 12 which is not a prime.

Will an offspring show a recessive trait if only one of its parent has the gene for that trait?
A family tree is a great idea, but the science is based on probability. The probability that a recessive trait will show up in a family is 25% if both parents are carriers. In order for a recessive trait to show up in a person, he/she must inherit a copy of the recessive trait from both parents. If one parent is recessive, let's say "rr" and the other parent is a carrier, say "Rr", the probability is 50%. If both parents are recessive, the probability is 100% (rr x rr). If neither parent carries the trait the probability is 0% (RR x RR). BUT, this only tells you what MIGHT happen. We all know that the probability of having a boy is 50:50, but we all know families of all boys. So it would be interesting to see if the probability works out in your family. If you do a search on the web for "genetics" or "probability and genetics" you will get plenty of hits. vanhoeck

What is the probability that the sum of the dice is odd and both dice show the number 3?
The probability is 0. If both dice show the number 3 then the sum is 6 which is not odd.
How many times would a coin have to show heads in 50 tosses to show an experimental probability of 20 percent more than the theoretical probability of getting heads?
Theoretical probability = 0.5 Experimental probability = 20% more = 0.6 In 50 tosses, that would imply 30 heads.
