Adie is rolled 20 times. find the probability of getting exactly four two's out of 20 attempts.

First find the probability of getting four twos in a row.

(1/6)^4*(5/6)^16

Then you would multiply this probability by the number of combinations of those four twos in a sequence of 20 attempts

20!/(4!(20-4)!)

And the product of the probability times the number of combinations is:

(1/1296)(152587890625/2821109907456)4845 :P which is approximately:

0.2022  or 20.22% to the nearest hundredth of a percent.

Your answer would be ahere is how: perimeter is how long all the sides are. in a rectangle, there are two sets of parallel sides. so, to find this, we would to the following.(15x2)+(4x2)30+838if you have questions ask! and mark me brainliest! i really wanna level up : 3
