The probability that he does not wait for more than five minutes all 5 days this week is 0.16807
<h3>How to determine the probability?</h3>
The probability that he waits for more than 5 minutes is:
p = 30%
This means that the probability that he does not wait for more than 5 minutes is
q = 70%
If he does not wait for more than five minutes all 5 days this week, the probability is:
P = q^5
This gives
P = (70%)^5
Evaluate
P = 0.16807
Hence, the probability that he does not wait for more than five minutes all 5 days this week is 0.16807

to simplify the fraction you must first find the number that goes into both numbers, in which is 7;
So divide both the numerator and the denominator by 7;
35 ÷ 7 = 5
21 ÷ 7 = 3
So your final answer would be;
35/21 = 5/3 = 1 2/3 (in simplest form)
