Answer:
P(D) = 0.3
Step-by-step explanation:
P(A) = 0.5
P(D|A) = 0.6
P(D) = P(A) * P(D|A)
P(D) = 0.5 * 0.6 = 0.3
<span>Abstinence (from heterosexual sex) is the only method listed that is 100% effective at preventing pregnancy. When the other methods are used for pregnancy prevention during sex between a sperm-producing body and an egg-producing body, there is the possibility that some sperm will still come into contact with an egg.</span>
Is that even possible
0.0001 maybe?

Answer:
The probability of taking $ 2.5 is 12.2%
Step-by-step explanation:
To make $ 2.5 with only 3 coins, you have to take out 2 $ 1 coins and a $ 0.5 coin in one of the following 3 ways:
(1) (1) (0.5) = (2.5) (i)
(1) (0.5) (1) = (2.5) (ii)
(0.5) (1) (1) = 2.5 (iii)
There are 3 coins (1)
There are 9 coins (0.5)
Therefore, the probability of drawing a coin from (1) on the first attempt is 3/12
The probability of drawing a coin of (0.5) on the first attempt is 9/12.
Then, the probability of drawing $ 2.5 from the form (i) is:
Finally:
P ($ 2.5) = P (i) U P (ii) U P (iii)
P ($ 2.5) = P (i) + P (ii) + P (iii)
P ($ 2.5) = 3P (i)
P ($ 2.5) = 3 * 0.0409
P ($ 2.5) = 12,227
The probability of taking $ 2.5 is 12.2%
