They are practically synonyms, but expecting is knowing a certain probability of an event occurring, while looking forward to is having affect toward an event occurring.
In a family with four children, the probability of having four boys is 1 in 16.
To determine the probability of selecting a family with exactly 3 male children out of 4, we can use the binomial probability formula. The probability of having a male child is typically considered to be 0.5 (assuming an equal likelihood of male and female). The probability of exactly 3 males in 4 children is calculated as ( P(X = 3) = \binom{4}{3} (0.5)^3 (0.5)^1 = 4 \times 0.125 \times 0.5 = 0.25 ). Thus, the probability is 0.25 or 25%.

Since having a child to a child is an independent event (assuming no outside intervention), the probability is still about 50 / 50 boy or girl.
The probability of a boy is still 0.5 no matter how many prior children there are.
Since the probability of having a son is about 1/2, the probability of the first 4 children being boys is about (1/2)4.
The probability of having a male or female baby is generally considered to be roughly equal, with about a 50% chance for each gender. While biological factors can influence this ratio slightly, the overall probability in large populations tends to balance out to close to 1:1. Therefore, for any individual pregnancy, the chance is approximately 50% for a male and 50% for a female.
