Question

a bag contains 15 black, 17 green, 22 pink, and 29 yellow tokens. you pick one token at random. find the probability that it is not black. p(not black) = \frac{?}{}

Explanation:

Step1: Calculate total number of tokens

Total tokens \(=15 + 17+22 + 29=83\)

Step2: Calculate number of non - black tokens

Non - black tokens \(=17+22 + 29=68\)

Step3: Calculate probability

Probability \(P(\text{not black})=\frac{\text{Non - black tokens}}{\text{Total tokens}}=\frac{68}{83}\)

Answer:

\(\frac{68}{83}\)
