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) = ?
Answer
Answer:
$\frac{68}{83}$
Explanation:
Step1: Calculate total tokens
$15 + 17+22 + 29=83$
Step2: Calculate non - black tokens
$17+22 + 29 = 68$
Step3: Calculate probability
$P(\text{not black})=\frac{68}{83}$
