We check 15 bananas. Six of the bananas are bruised. Recall the Definition of Probability: If all outcomes of an experiment are equally likely, then the probability is given by,
Probability of an event or = ‘Number of favorable outcomes/Total number of possible outcomes
(a) From the given statement the total number of bananas are 15 and 6 number of bananas are bruised.
Therefore, the experimental probability that « banana. is bruised is
$$\displaystyle\frac{{6}}{{15}}=\frac{{2}}{{5}}$$
(b) Also, there are 15 — 6 = 9 number of bananas are not bruised. Thus, the experimental probability that « banana is not bruised is
$$\displaystyle\frac{{9}}{{15}}=\frac{{3}}{{5}}$$
$$\displaystyle{a}.\frac{{2}}{{5}}{b}.\frac{{3}}{{5}}$$
