Solution

The correct option is C

Q. Examine the following statements and comment:
If two coins are tossed at the same time, there are

3

possible outcomes- two heads, two tails, or one of each. Therefore, for each outcome, the probability of occurrence is

1 / 3

Q. Examine each of the following statements and comment:

(i) If two coins are tossed at the same time, there are 3 possible outcomes−two heads, two tails, or one of each. Therefore, for each outcome, the probability of occurrence is 1/3.

(ii) If a die in thrown once, there are two possible outcomes − an odd number or an even number. Therefore, the probability of obtaining an odd number is 1/2 and the probability of obtaining an even number is 1/2.

Q. Assertion : Two dice are thrown simultaneously. There are 11 possible outcomes and each of them has a probability

\frac{1}{11}

.
Reason : Probability of an event (E) is defined as P(E)

= \frac{N u m b e r o f f a v o u r a b l e o u t c o m e s}{T o t a l n u m b e r o f p o s s i b l e o u t c o m e s}
