Answer:
s = 11
Step-by-step explanation:
Given
=
( cross- multiply )
8(s - 2) = 72 ( divide both sides by 8 )
s - 2 = 9 ( add 2 to both sides )
s = 11
Answer:
a) α should be larger than β
Step-by-step explanation:
a) Refer to the diagram attached to the bottom of this answer. Given that the tumor is cancerous (that is saying that α happens), there are other events different than β in that event space, so β should be smaller than α.
b) Using the diagram again, we can see that the probability of β happening is the product of α and the probability that the coin shows tails, which is 0.5, then:
β = 0.5·α
which proves β is half of α, hence α is larger.
