Answer to Problem 43STP

The probability of getting a red marble drawn at random is $0.33$ .

Explanation of Solution

Given information:

A box contains $7$ blue marbles, $6$ red marbles, $2$ white marbles and $3$ black marbles.

Calculation:

As from the given information, a box contains $7$ blue marbles,
