Question

There are 6 marbles in a box with numbers from 1 to 6 marked on each of them.What is the probability of drawing a marble with number 4?​

Answer 1

Answer:

Solution:

Total number of marbles = 6

So n(s) = 6

Number of marbles marked with 2 = 1

n(e) = 1

Probability = \frac{Number\ of\ favourable\ outcomes}{Total\ number\ of\ outcomes}\

Total number of outcomes

Number of favourable outcomes

=\ \frac{n\left(e\right)}{n\left(s\right)}\ =\ \frac{1}{6}=

n(s)

n(e)

=

6

1

ii) Total number of marbles = 6

n(s) = 6

Number of marbles marked 5 = 1

n(e) = 1

Probability = \frac{Number\ of\ favourable\ outcomes}{Total\ number\ of\ outcomes}\

Total number of outcomes

Number of favourable outcomes

=\ \frac{n\left(e\right)}{n\left(s\right)}\ =\ \frac{1}{6}=

n(s)

n(e)

=

6
