<span>I am assuming the gender of each child is independent of the other.
Then the information about the first three children is irrelevant.
So then the probability of fourth child being boy is 1/2, since </span><span>boys and girls are equally likely</span><span>.
Hope this helps.</span>
Step-by-step explanation:
you will just use your formula
l×b
and your answer will be
122.85
Answer:
Factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12. A positive integer greater than 1, or an algebraic expression, that has only two factors (i.e., itself and 1) is termed prime; a positive integer or an algebraic expression that has more than two factors is termed composite. The prime factors of a number or an algebraic expression are those factors which are prime. By the fundamental theorem of arithmetic, except for the order in which the prime factors are written, every whole number larger than 1 can be uniquely expressed as the product of its prime factors; for example, 60 can be written as the product 2·2·3·5.
-1.5 + k is the same thing as k - 1.5
and if we want to get k all by itself, we need to add 1.5 on both sides, not add -1.5
so
-1.5 + k = 8.2
-1.5 + 1.5 + k = 8.2 + 1.5
k = 8.2 + 1.5
k = 9.7
