Answer:
A. -1/5
Step-by-step explanation:
-7-(-5) /5-(-5)
= -7+5 / 5+5
= -2/10
-1/5 option A
Since they are independent events to find the probability of both is P(A) * P(B)
P(A) = P(Heads) =

P(B) = P(Roll ≥ 4) =

Now multiply those fractions together

= P(Heads & ≥ 4)
1 is 10 dimes that is what I’ll do
58^(1/2) is √58 if that is what you meant
