Question

i) The first term of ar
v) A box contains 5 red, 8 blue and 3 green pens. What is the probability that the pen
picked up is blue?
​

Answer 1

Answer:

probability of blue pen is  = number of blue pens/total number of pens

=8/(5+8+3)

=8/16

=0.5

Probability that the pen  picked up is blue =0.5

Answer 2

Answer:

P(blue) =1/2

Step-by-step explanation:

Total No of possible outcomes=(5+8+3)=16

For picking up a blue pen,

No of favourable outcomes=8

P(picking up a blue pen) = No. of favourable outcomes/Total No. of possible outcomes

=8/16=1/2
