Astandard number cube is tossed. find p(3 or odd)

0.5 or 1/2

Step-by-step explanation:

Let A be the event that the number cube is 3 or odd as 3 is also an odd number. So the event space will be:

{1,3,5}

The total number of outcomes are 6 as in:

{1,2,3,4,5,6}

So the probability of tossing 3 or odd number will be:

P(A) = n(A) / n(S)

= 3/6

=1/2

Hence the probability in fraction form is 1/2 and in decimal form is 0.5 ..
