Step-by-step explanation:
Your answer would be C. 27/190.
This is because the probability of choosing green as the first marble would be 9/20, as there are 20 marbles in total and 9 of those are green.
The probability of choosing a red marble as the second marble would be 6/19, as no red marbles would have been lost if green was picked first, but there would be one less marble in total.
The 'and' rule for probability, the one that is used to determine the probability of P(A) and P(B), is to multiply, so we need to do 9/20 × 6/19 = 54/380 = 27/190.
I hope this helps!
Whats up? What do you need help with
Answer:
No
Step-by-step explanation:
Assuming that you put the wrong sign for the second equation if you plug (2,7) into the two equations it only works for one equation.
Answer:
18pi units is the circumference
81pi units² is the area
Step-by-step explanation:
Radius² = (-2-7)² + (2-2)² = 9²
Radius = 9
Circumference = 2pi×r
= 18pi
Area = pi × r²
= 81pi
