Answer:
P (arts) = 0.25
P (psychology) = 0.25
P (geology) = 0.5
Step-by-step explanation:
Let the probability of choosing art = x
As given that she is equally likely to choose art or psychology and twice as likely to choose geology.
So,
P (arts) = x = P (psychology)
P (geology) = 2x
The sum of the probability = 1
So,
P (arts) + (psychology) + P (geology) = 1
x + x + 2x = 1
<u>x = 0.25</u>
<u>P (arts) = x = 0.25</u>
<u>P (psychology) = x = 0.25</u>
<u>P (geology) = 2x = 2*0.25 = 0.5</u>
