Question

2. A glass jar contains 6 red, 5 green, 4 blue and 5 yellow marbles of same size. Hari takes out a marble from the jar at random. What is the probability that the chosen marble is of red colour? Please steps​

Answer 1

Answer:

The probability of chosen marble is of red colour is 3:10

Step-by-step explanation:

According to the question, there are 6 red, 5 green, 4 blue and 5 yellow.

so, total number of outcomes are = 6+5+4+5=20

Number of favourable outcomes are=6

probability for the marble to be red= number of favourable outcomes : total number of favourable outcomes

P(red)= 6:20

P(red)= 3:10

Hence, the probability of chosen marble is of red colour is 3:10.
