Question

If a bag contains 4 twix, 5 snickers and 8 milky way...

Select one candy bar, observe the outcome, replace it and select another one. Calculate the probability of choosing two twix??

Answer 1

There are 17 candy bars (4 Twix, 5 Snickers, and 8 Milky Way) in the bag.

P(T₁T₂) = P(T₁)*P(T₂) = (4/17)*(4/17) = 16/289 = 0.0554

The probability of picking 2 Twix candy bars with replacement is about 0.0554.
