Answer 1

EXPLANATION

Let's see the facts:

Bag contains:

30 blue beads

10 red beads

35 yellow beads

A bead is randomly pulled out from the bag

The Probability equation is given by the following expression:

`\text{Probability}=\frac{Number\text{ of favourable outcomes}}{\text{Total number of outcomes}}`

The content in the bag = 30 blue beads + 10 red beads + 35 yellow beads = 75 total beads

To pull a bead from the bag= 75 ways

To pull two red beads out of the bag = 10 ways

So, P(Red and Red) without replacement = 10/75 * 9/74 = 3/185

So, the answer is 3/185
