The number of girls in the 14 newborn babies selected is a binomially distributed random variable with n = 14 and p = 0.5. And we know that the binomial probability distribution is given by
P(X = k) = (nCk) p^k (1–p)^(n-k)
So, P(X = 0) = (14C0) • 0.5^0 • (1–0.5)^(14-0) = 0.000
P(X = 1) = (14C1) • 0.5^1 • (1–0.5)^(14–1) = 0.001
And so on.
Thus, P(X = 4) = (14C4) • 0.5^(4 • (1–0.5)^(14–4) = 0.061
So the probability of selecting exactly 4 girls is 0.061.
Answer:
2
Step-by-step explanation:
You first turn 6/16 into a decimal which is 0.5625, then you round that to the nearest whole number. To find decimal divided 6 by 16. 0.<u>5</u> is rounded to 1 because numbers over 5 round up and number below five round down. Then 1 + 2 = 3.
