Answer:
3.5
Step-by-step explanation:
5(14-2)^2/2
5( 12)^2/2
Do the exponent
5(12*12)/2
5(144)/2
144/2= 72
72*5= 360
Answer : 360
To see if two events are independent you can use the formula P(a|b) = P(a)
In this problem P(C|Y) = 35/75 = .4667 and P(C) = 110/300 = 3.667,
therefore C and Y are not independent events because P(C∣Y) ≠ P(C).
The answer is choice D
its 13
Its 13 A
