Answer:
0.19
Step-by-step explanation:
Given that :
Total possible outcomes = 10
If the same name can be chosen twice, then probability is with replacement ;
Probability = required outcome / Total possible outcomes
Required outcome = number of Collins in name = 1
Probability of choosing Collins atleast once ;
2[P(Collins) * P(not Collins)] + P(Collins) * P(Collins)
P(colins) = 1/10
P(not Collins) = 9/10
2(1/10 * 9/10) + (1/10 * 1/10)
2(9/100) + (1/100)
18/100 + 1/100
19/100
= 0.19
