Answer:
total = 4+6+2 = 12
probability of choosing red = possibility/total number .
=6/12
= 1/2
probability of choosing blue = 2/12
= 1/6
as they gave probability of red or blue , we need to add both the outcomes .
1/2 + 1/6
TAKING LCM !
=3/6 + 1/6
=4/6
=2/3
=0.67
Step-by-step explanation:
SO YOUR ANSWER WILL BE OPTION (b) .
THANK YOU :)
