An urn contains three red balls numbered 1, 2, 3, four white balls numbered 4, 5, 6, 7, and three black balls numbered 8, 9, 10. A ball is drawn from the urn. What is the probability that

(a) it is red?

(b) it is odd-numbered?

(c) it is red and odd-numbered?

(d) it is red or odd-numbered?

(e) it is not black?

**(a)**

To determine

**To calculate:** The probability of drawing a red ball if a ball is drawn at random from the urn. An urn contains three red balls numbered 1, 2, and 3, three black balls numbered 8, 9, and 10 and four white balls numbered 4, 5, 6, 7.

**Given Information:**

A ball is drawn at random from the urn. An urn contains three red balls numbered 1, 2, and 3, three black balls numbered 8, 9, and 10 and four white balls numbered 4, 5, 6, 7.

**Formula used:**

The probability of an event occurring *k* times out of *n* equally likely ways, then,

**Calculation:**

Consider the event of drawing a red ball to be *R*.

There are 10 balls in the urn, thus,

**(b)**

To determine

**To calculate:** The probability of drawing an odd-numbered ball if a ball is drawn at random from the urn. An urn contains three red balls numbered 1, 2, and 3, three black balls numbered 8, 9, and 10 and four white balls numbered 4, 5, 6, 7.

**(c)**

To determine

**To calculate:** The probability of drawing a ball that is red and odd-numbered ball if a ball is drawn at random from the urn. An urn contains three red balls numbered 1, 2, and 3, three black balls numbered 8, 9, and 10 and four white balls numbered 4, 5, 6, 7.

**(d)**

To determine

**To calculate:** The probability of drawing a ball that is red or odd-numbered ball if a ball is drawn at random from the urn. An urn contains three red balls numbered 1, 2, and 3, three black balls numbered 8, 9, and 10 and four white balls numbered 4, 5, 6, 7.

**(e)**

To determine

**To calculate:** The probability of drawing a ball that is not black ball if a ball is drawn at random from the urn. An urn contains three red balls numbered 1, 2, and 3, three black balls numbered 8, 9, and 10 and four white balls numbered 4, 5, 6, 7.
