1.
On the average, batsmen in a certain cricket team make a scoring shot on every third ball.
a) what is the probability that in a particular 6 ball over, scoring shots will be made on at least 3 Balls?
b) in 200 overs how many overs would we expect 2 scoring shots to occur?
Part a = 233/729
Need help with part b!

2.
A die is loaded such that in 8 throws, the probability of getting 3 even numbers is four times the probability of getting 2 even numbers. Find the probability that a single throw of the die results in an even number.
