Answer:
The probability of tail occurs =
= 0.25
and
The probability of heads occurs =
= 0.75
Step-by-step explanation:
Given:
Let P be the tail as outcome in a toss.
Heads is three times as likely to come up as tails.
So, Probability of getting heads = 3P
The total probability is 1
So, P + 3P = 1
4P = 1
P =
= 0.25
We denoted P as the probability of getting tail in a toss.
So probability of getting heads = 1 -
= 
Therefore, the probability of tail occurs =
= 0.25
and
The probability of heads occurs =
= 0.75
