Lori downloaded all the pictures she took at rita’s wedding into a single computer folder. she took 86 of the 134 pictures with her camera and the remainder of them with her cell phone. of the pictures lori took with her cell phone, one out of every five was blurry. to the nearest whole percent, what is the probability that when she opens a random picture from the computer folder, it will be a blurry picture she took with her cell phone? 7% 13% 31% 56%

Lori took  of the pictures with her camera.

That means the remaining pictures were taken with her cell phone.

(134 - 86 = 48, which means  of the pictures were taken with her cell phone.)

If  of the 48 pictures she took with her cell phone were blurry, that means the probability of Lori opening the computer folder and opening a random picture that is blurry and AND taken with her cell phone is 7%.

This is because ( × ) × 100 = 7.16%.

(Tip: the word 'and' in probability means 'multiplied by'. So if it's asking for the probability of a blurry picture () AND a picture taken with her cell phone (), you should multiply the two together.)

The answer is n divided by -5 + 1
