The question tells us that Mallory's 2 years old than three times her brother Jake's age, but let's just start by saying she's 2 years older than <em>some age. </em>What would that look like? Well, we'd be taking some number and adding two to it, so something like this:
Mallory's age = (some age) + 2
What is that age though? The problem tells us it's three times Jake's age, j. We can write that as 3 × j, or 3j, to save space. Filling in our blank, we can write the expression for Mallory's age as 3j + 2

Answer:
option d
Step-by-step explanation:
Given that a coin is tossed 5 times. Assuming it is a fair coin, head and tail are equally likely.
If we toss 5 times, the number of heads can be either 0 or 1 or 2...5.
Number of outcomes that have 2 heads
=out of 5, two heads and three tails
=5C2
=5(4)/2
=10
So answeris 10
