Answer:
0.98
Step-by-step explanation:
Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.13 + 0.85 - 0
P(A or B) = 0.98
Note that P(A and B) is 0. This is because we are told A and B are mutually exclusive events. This means both events cannot happen simultaneously. An example would be flipping a coin to have it land on heads and tails at the same time.
35 to the second power would be the same as multiplying 35 by itself so.....
Ex. 35 to the second power would be
35x35
35 to the third power would be
35x35x35
35 to the fourth power would be
35x35x35x35
And etc.
35x35=1,225
x + x + 2 + x + 4 <= 126 (where x is the first of the numbers)
3x <= 120
x <= 40
So the numbers are 40 , 42 and 44.
