Question

Consider a political discussion group of 8 democrats, 8 republicans and 6 independent suppose the teo groups meme bet are randomly selected in succession to attend a policial convection find the probability of selecting two demo

Answer 1

Answer:

The probability of selecting two democrats is 1/380

Step-by-step explanation:

• Probability is the branch of mathematics that deals with numerical descriptions of how likely an event is to occur.
• Probability of an event = Number of favourable outcomes / Total number of outcomes.

Here we are given the people as,

8 democrats, 8 republicans and 6 independent.

So total number of people are: 8+6+6=20

Probability of choosing first democrat = 1/20

Probability of choosing first democrat = 1/19

Thus P( two democrats in succession ) = 1/20 ×1/19

                                                                = 1/380
