Question

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

hint : just multiply both the probabilities as both are independent
P(AB)=P(A)P(B)

Answer 2

2/5?

Answer 3

thats right !

Answer 4

On a die numbered 1 to 6, What is the probability of rolling a 2 three times in a row.

Answer 5

again you have to multiply probability of each event. as the experiment is fresh each time.

probability of rolling a 2 first time : 1/6
probability of rolling a 2 second time : 1/6
probability of rolling a 2 third time : 1/6

probability of rolling a 2 all 3 times = ?

Answer 6

1/72?

Answer 7

hmm...

1/6^3 = ?

Answer 8

1/6?
