Question

Consider a bag containing four fair dice:

A blue four-sided die,
A red six-sided die,
A blue six-sided die, and
A blue ten-sided die.
In what follows, you may assume that the dice are always chosen uniformly.

Answer 1

The probability of drawing a blue marble from a bag containing four blue and three white marbles is 4/7.

Step-by-step explanation:

Probability of Drawing a Blue Marble

In this problem, we are asked to find the probability of drawing a blue marble from a bag containing four blue and three white marbles. Since Maria draws the marble randomly, we can assume that each marble has an equal chance of being drawn. There are a total of seven marbles in the bag, so the probability of drawing a blue marble on the first draw is 4/7.
