Answer:
0.9 or 90%
Step-by-step explanation:
The probability of an event not happening is equivalent to 1 minus the probability of that event happening.
P(~x) = 1 - P(x)
Since the given probability is 10%, we substitute this value to the formula.
P(~x) = 1 - 10%
P(~x) = 1 - 0.1
P(~x) = 0.9 or 90%
Hope this helps!
