What is the probability that all four of the selected chips have the same color? [AJ 0.0427 [B] 0.1312 [C] 0.2049 D) 0.3688 [E] 0.7524 16. What is the probability that two chips of each color are selected? A] 0.0427 [B] 0.1312 [C] 0.2049 D] 0.3688 E] 0.7524Explanation / Answer
Ans:
Probability of getting blue chips=5/11
13)P(4 blue chips)=(5/11)^4=0.0427
Option A is correct
14)P(3 blue chips)=4C3*(5/11)3*(6/11)1
=0.2049
Option C is correct.
15)P(all same color)=P(all are blue)+P(all are yellow)=(5/11)^4+(6/11)^4=0.1312
Option B is correct.
16)P(2 are blue and 2 are yellow)=4C2*(5/11)^2*(6/11)^2=0.3688
Option D is correct.
