Answer:0.04247,6

Step-by-step explanation:Given that a biased coin has a 0.6 chance of coming up heads when flipped

X no of coins which showed head is binomial with p = 0.6 since each trial is independent of the other

When there are 10 flips we have n =10

This gives

probability of flipping 3 or fewer heads in 10 flips.

=

Expected number of heads in 10 flips
