Answer:
a) 0.72
b) 0.98
Step-by-step explanation:
We are given the following information in the question:
P(passing maths exam) = P(m) = 0.9
P(passing Spanish exam) = P(s) = 0.8
It is assumed that the results of the two exams are independent of each other.
a) probability that she passes both exams
By assumption of independence, we can write:

0.72 is the probability that Josie will pass both the exams.
b) probability that Josie passes at least one of the exam

0.88 is the probability that Josie passes at least one of the exams.
Answer:
5x - 5
Step-by-step explanation:
To find the missing side, add the two sides together and subtract them from the perimeter.
side 1 + side 2
3x + 2 + 8x + 7
combine like terms
11x + 9
Subtract from the perimeter
16x + 4 - (11x + 9)
rewrite as an addition problem, so you need to change the signs inside the parentheses.
16x + 4 + (-11x -9)
Now combine like terms
5x - 5
