Question

Find the probability of randomly choosing three brown M&Ms in a row from a bag that contains 35 brown M&Ms out of 250 M&Ms total. Note that as you choose them, you immediately eat them.Question 4 options:0.08570.0120.420.00254

Answer 1

We have to find the probability of each trial.

`P_1=(35)/(250)`

In the first trial, we have 35 browns M&ms in total.

`P_2=(34)/(249)`

Then, we have 34 browns and 249 in total because we ate one.

`P_3=(33)/(248)`

We reduce again the events and the total outcomes because we ate another M&M.

Now, we have to multiply all of them

`P=(35)/(250)*(34)/(249)*(33)/(248)=(35*34*33)/(250*249*248)=(39,270)/(15,438,000)=0.00254`

Hence, the last option is the correct answer.
