84 feet because you would just add the 70 and 14 together
Answer:
0.099, 0.969,0.87,8.3.1.063
Step-by-step explanation:
Let X be the left handed people in the sample of 10 people selected.
X is binomial with n=10 and p = 0.13
a) the probability that there are exactly 3 lefties in the group
=
b) the probability that there are at least 3 lefties in the group
=
Now Y number of right handers is binomial with n =10 and p = 0.87
c) the expected number of right-handers in the group.

d) the standard deviation of the number of right-handers in the group
=
In a linear functions, f(x)=mx+b, your y-intercept is b. So any function that is any number times x plus 3 is going to give you a y intercept of 3.
