Question 39637
Suppose that an experiment is repeated four times. A certain event has probability
OF WHAT ?OCCURRENCE OR NON OCCURRENCE?ASSUMING IT IS FOR OCCURRENCE
1/10 in a single repetition of the experiment.  What is the probability that it never occurs?
P(O)=1/10=0.1....P(NO)=9/10=0.9
LET US FIND PROBABILITY OF NO OCCURRENCEIN 4 TRIALS =(0.9)^4
