Need help figuring this out. Thank you 9

5 people are randomly selected and their dominate hand was recorded. Assume each person's dominate hand is independent of the next and P(L)=0.10, P(~L)=0.90. Let X be the number of people that are left-handed. What is the variance corresponding to X? O 0.10 O 0.45 O 0.50 O 0.67
