Abiased coin has a 0.6 chance of coming up heads when flipped. find the probability of flipping 3 or fewer heads in 10 flips. what is the expected number of heads in 10 flips

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

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
