If you were told that you had a bag of 11 balls containing 4 blue, 2 white, 5 yellow balls, and you would win $100 if you selected either a white OR a blue ball. What operation do you think you would use for the probabilities of the blue and white balls?

Respuesta :

The probability of randomly selecting a ball that is either white or blue is: P =  6/11

How to get the probability?

Here we want to get the probability of randomly selecting a ball that is either whiter or blue.

This will be equal to the quotient between the number of balls that are either white or blue, and the total number of balls in the bag (where we assumed that each ball in the bag has the same probability of being randomly selected).

There are 11 balls in the bag.

2 are white, and 4 are blue.

So the probability of randomly selecting a ball that is either white or blue is:

P = (2 + 4)/11 = 6/11
