Answer:
d) 0.4
Step-by-step explanation:
P(Ra) = 0.998
P(Rb) = 0.995
P(A) = 0.4
P(B) = 0.6
The probability that method A was performed, given that the eye was recovered within a month of the surgery, is determined by the probability that the eye recovered within a month with method A (P(A) x P(Ra)),divided by the probability that the eye recovered within a month with either method (P(A) x P(Ra) + P(B) x P(Rb)):
The probability that method A was performed is 0.40.
Answer:
164ft ^2
Step-by-step explanation:
The entire rectangle is 300ft^2. The nonshaded areas are triangle so if you find the area of the triangles and subtract you will get the area of the shaded region. Using 1/2bh should help you find the area of the triangles.
Answer:
165920160 ways
Step-by-step explanation:
Number of songs in library (n) = 115
Number of songs in Playlist (r) = 4
Since the order is important:
nPr = n! / (n-r)!
115P4 = 115! / (115 - 4)! = 115! / 111! = (115 * 114 * 113 * 112)
= 165920160 ways
