Prob (8) = 4/52 = 1/13
Prob(Queen) = 4/52 = 1/13
Prob ( 8 then a queen) = 1/13 * 1/13 = 1/169 answer
The probabilities are multiplied beause the 2 events are independent
Answer:
Step-by-step explanation:
So you have 12 cases delivered in 1 hour and 30 minutes. 30 minutes is half of an hour or .5
so 12/1.5 is 8, that is 8 cases per hour for a total of 32 cases in 4 hours.
This is an easy half-life problem.
Every half-life, a substance loses half its radioactivity. So, after 2 half-lives, a substance will have a quarter of its radioactivity.
2 * 5,700 = 11,400 years
