Question

there are 6 red pens and 4 blue pens in a box with equal size. a pen is taken out randomly. find the probability of getting a red pen and find the probability of not getting a red pen? ​

Answer 1

Step-by-step explanation:

total no. of outcomes= 6+4=10

red pens=6

blue pens =4

favourable outcomes=10-6=4

probability=favourable outcomes/total no of outcomes

=4/10

or 0.4or 25%

Answer 2

Answer:

here ,

no of possible outcome = total number of blue pen + total number of red pen

= 10

no . of favourable outcome = 6

probability for getting the red pen = 10 / 6

= 5/3 ans

² ..probability of not getting the red pen =probability of blue pen

probability of getting blue pen = 10 / 4

= 5/2
