Question

(10) A box contains 4 red, 6 blue and 5 green pens. What is the probability that
the pen picked up is (a) blue (b) red (c) not blue. Complete the following
activity to find the answer.​

Answer 1

Answer:

(a) =Total no of outcome=15

favourable no of outcome=6

probability=6/15

(b) =favourable no of outcome=4

probability=4/15

(C) favourable no of outcome=9

probability=9/15

Answer 2

Answer:

The probability that the pen picked up is blue is 6/15, red is 4/15 and not blue is 9/15.

Step-by-step explanation:

Number of red pens = 4

Number of blue pens= 6

Number of green pens = 5

So, the total number of pens = 4+6+5= 15

Probability(Event) = Favorable Outcomes/Total Outcomes = x/n

(A) So,the probability that the pen picked up is blue is:-

Number of blue pens = 6

Total number of pens =15

So, the probability is= 6/15

(B) So,the probability that the pen picked up is red is:-

Number of red pens = 4

Total number of pens =15

So, the probability is= 4/15

(C) So,the probability that the pen picked up is not blue is:-

Number of red pens = 4 + Number of green pens = 5

Total number of pens which are not blue= 5+4=9

Total number of pens =15

So, the probability is= 9/15
