Answer:
1 / 8568
Step-by-step explanation:
The number of combinations is:
₁₈C₅ = (18! / (5! (18−5)!)
₁₈C₅ = 8568
There are 8568 possible groups of 5 that can be selected from 18. Only 1 of those groups contains the five youngest students. So the probability is:
P = 1 / 8568 ≈ 0.0117%
So you want to add 18500+9%=20,165 and then divide 20165 by 48 and you get 420.10
Answer:
78% probability that a randomly selected online customer does not live within 50 miles of a physical store.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that:
Total outcomes:
100 customers
Desired outcomes:
A clothing vendor estimates that 78 out of every 100 of its online customers do not live within 50 miles of one of its physical stores. So the number of desired outcomes is 78 customers.
Using this estimate, what is the probability that a randomly selected online customer does not live within 50 miles of a physical store?

78% probability that a randomly selected online customer does not live within 50 miles of a physical store.
