Question

Let A and B be independent events with P(A) = 0.1 and P(B) = 0.8. What is P(A and B)? Enter your answer in the box below as a decimal, such as 0.34. Do not round. P(A and B) What is the probability of rolling a 1 on every dice when you roll 6 six- sided dice? Enter your answer in the box below as a fraction, such as 1/344. There is a 40% probability that Bob will get a promotion and a 10% probability that Tom will get a promotion. Assuming that the probabilities that Bob and Tom will be promoted are independent events, find the probability that both Bob and Tom will NOT get a promotion Enter your answer in the box below as a decimal, such as 0.23. Do not round. Check Answr

Explanation / Answer

a)P(A)=0.1 and P(B)=0.8

for the independent events, P(A and B)=P(A)*P(B)=0.1*0.8=0.08

b) 1/6

c) P(B)=0.4 and P(T)=0.1

P(B and T)=0.4*0.1=0.04

thus P( none)=1-0.04=0.96
