b) 2/3
c) 1/2
d)1/4

Answer 1

Answer:

there are two positive integers a and b. the probability that a+b is odd will be: is b) 2/3 or

c) 1/2

Answer 2

Given:

there are two positive integers a and b.

To Find:

the probability that a+b is odd will be:

a) 1

b) 2/3

c) 1/2

d)1/4

Solution:

Probability means how likely an event is going to happen out of all the possible outcomes for the event. It lies from 0 to 1. It is denoted by 'p', The formula to find probability is,

$P=\frac{PossibleOutcomes}{Total Outcomes}$

Now any two positive integers added together will either give an odd or an even number, so we can say that the total possible outcomes are 2 (odd, even) and the probability to get an odd will be,

$P=\frac{1}{2}\\=0.5$

Hence, the correct option is (c).
