Pedro has gotten on base 4 out of the last 5 times he was a bat. He scores 50% of the time he gets on base. What is the probability that Pedro will get on base and score on his next at bat

Answer 1

well its simple multiply

P(on base) x P(scoring) = 4/5 x 1/2

Answer 2

ok

Answer 3

0.4

Answer 4

yep... so the question is saying if you get of base 4/5 = 80% and you score on 1/2 or 50% of times then half of 80% is 40% or 4/10 or 0.4

On nights when it rains, the probability that Kim will go to soccer is 2/5. Tonight there is a 60% chance of rain. What is the probability that she will go to her soccer game

Answer 28

I take it there is a 100% chance she'll go if it doesn't rain. So..

60% is 3/5

so there are two choices, rain or no rain.

If it rains the probability that she'll play is 2/5

so the chance of her going if it rains is (2/5)(3/5) = 6/25
