Ans: Correct Option is (C) =>
P =
Step-by-step explanation:
According to the definition of probability:
Probability of an Event = (Number
of favorable outcomes) /
(Total
number
of possible outcomes or sample space)
or,
P = O / S;
First let us find Total number of Possible Outcomes(S):
= 12
(Since a student can choose two electives)
In mathematical terms, you can read S as:"The sample space is equals to the combination of 12 taken 2."
Number of favourable outcomes(O):
O = (3-art-electives)
* (4-history-electives)
O = (3
)(4
)
In mathematical terms, you can read O as:"The outcome is equal to combination of 3 taken 1 times combination of 4 taken 1."
Hence,
Probability P = O/S
P =
