Find the m∠Z.

12degrees
15.5
4.4
47.7

Using Sine rule,

The binomial distribution can be calculated as:
P(r out of n) = (nCr) (p)^r (q)^(n-r)
In this case, p = 0.46, q = 1 - 0.46 = 0.54, and n = 3 people, so the formula is:
P(r out of 3) = (3Cr) (0.46)^r (0.54)^(3-r)
For r = 0, P = 0.1575
For r = 1, P = 0.4024
For r = 2, P = 0.3428
For r = 3, P = 0.0973

Notice that adding up the 4 values of P gives a value of 1.
