<h2>
P(E) =
or, 0.6092</h2>
Step-by-step explanation:
Given,
There are 348 identical plastic chips numbered 1 through 348 in a box.
To find, the probability of reaching into the box and randomly drawing a chip number which is smaller than 213 = ?
Total number of possible outcomes = 348
Let E be the event of getting randomly drawing a chip number that is smaller than 213.
Favourable outcomes are:
1, 2, 3, .............., 212
Number of favourable outcomes = 212
∴ Probability =
P(E) =
=
or, 0.6092
Thus, P(E) =
or, 0.6092
