Answer:
6 times
Step-by-step explanation:
There are two events here:
1. Probability to hit snooze button= P(A) = 20%. Also mean P(A') = 80%
2. The probability to miss the bus= B
If Josiah hits the snooze button (A is happen), he misses the bus(B) 25% of the time. It mean P(B | A) = 25%
If Josiah doesn't hit the snooze button (A didn't happen), he won't miss the bus. It mean P (B | A') = 0%
If alarm woke Josiah 120 times , expected times that Josiah miss the bus will be:
P(B | A)* 120 * P(A) + P (B | A') * 120 * P(A') = 25%*20%*120 + 0% * 75%*120 = 6 times
8 = 2*2*2
9=3*3
We are finding the least common multiple
LCM = 2*2*2*3*3
LCM = 72
Sam and Carlos have each knocked down 72 pins

Step-by-step explanation:
They are dependent events, indicated by the word 'given'.
Answer:
Independent
dependent
Step-by-step explanation:
The scenario illustrates that the weight for people who exercises regularly tends is normal or below normal. It means that the weight of a person depends on how much a person exercises i.e. if person exercises more the weight is reduced and if not then weight will be gained. Thus, exercise is the independent variable while weight is dependent variable.
