Question

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?

Answer 1

Out of the 134 pictures Lori took at the wedding, 86 were taken with her camera and the rest with her cell phone. If one out of every five pictures taken with her cell phone was blurry, we can calculate the probability.

First, let's find the number of cell phone pictures Lori took: 134 - 86 = 48.

Next, let's find the number of blurry pictures taken with her cell phone: 48 / 5 = 9.6 (approximately).

Since we can't have a fraction of a picture, we round 9.6 to the nearest whole number, which is 10.

Therefore, the probability that when Lori opens a random picture from the computer folder, it will be a blurry picture she took with her cell phone is approximately 10%.
