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.
