If P(not event B) = 0.95, what is P(event B)?

The two events of B happening, or B not happening, are complementary events. One or the other must happen. There is no overlap so both events cannot happen simultaneously. This means the two probabilities add to 1, which represents 100%

P(event B) + P(not event B) = 1

P(event B) = 1 - P(not event B)

P(event B) = 1 - 0.95

P(event B) = 0.05

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
