If the probability of outcome “A” is .60, then the probability of “not A” is ____.
Added by Mary G.
Step 1
60, which means that out of 100 trials, "A" will occur 60 times. The probability of "not A" is the probability of any other outcome occurring besides "A". Since there are only two possible outcomes (either "A" or "not A"), the sum of their probabilities must Show more…
