Question

Out of 250 bulbs in a box 35 bulbs are defective one bulb is taken out at random from the box find the probability that the drown bulb is not defective

Answer 1

Answer: 43/50

Step-by step explanation

If 35 out of 250 are defective, this can be written in fraction form as 35/250.

If 35 are defective, the others will obviously be working so that will be 215 out of the 250. This can be written as a fraction (215/250)

This can then be simplified to 43/50

Answer 2

probability=

$\frac{214}{250}$
