Box has 10 M& M candies: 5 red and 5 blue.

Two candies are taken from this box.

Find the probability that the first randomly taken candy will be red and second will be red again.

Taken candy doesn't go back to the box.

Use formula: P (A and B) = P (A) * P (B)

Simplify final fraction.

If we use the formula P (A and B) = P (A) * P (B) and the data given we can say that the operation will be like this: P (Red and Blue) = 5 (total of candies) / 10 (it means 5 per 2 which are the 2 variable (blue and red)) + 5/10 = 10/10 or what is the same 1. The probability is 1
