Question

there are 498 identical plastic chips numbered 1 through 498 in a box. what is the probability of reaching into the box and randomly drawing a chip number that is greater than 315? express your answer as a simplified fraction or a decimal rounded to four decimal places.

1. The probability of reaching into the box and randomly drawing a chip number that is greater than 3150 is 0.3675
In this question we have been given there are 498 identical plastic chips numbered 1 through 498 in a box.
We need to find the probability of reaching into the box and randomly drawing a chip number that is greater than 315
Total number of chips = 498
so, n(S) = 498
Let event A: drawing a chip number that is greater than 315
The number of chips greater than 315:
498 – 315 = 183
So, n(A) = 183
The probability of reaching into the box and randomly drawing a chip number that is greater than 315 using the formula of probability,
p(A) = n(A)/n(S)
p(A) = 183/498
p(A) = 0.3675
Therefore, the required probability is 0.3675
