Question

Joe owns a stock which has probability .5 of going up. This morning, he bought a ticket in a lottery game which gives him a probability .0001 of winning. What is the probability that Joe's stock will go up and he will win in the lottery? Your answer should keep 5 positions to the right of the decimal, like .43212

Answer 1

Answer:

0.00005

Step-by-step explanation:

The probability of the stock going up and that of winning in the lottery are independent.

Hence, the probability of both = P(stock going up) × P(winning in the lottery) = 0.5 × 0.0001 = 0.00005
