What is the probability that a randomly-selected learner has three or moresiblings? (Your two classmates Lisa and Felix tried to answer. Below are theirsolutions.)FelixP(W > 3) = P(W = 3 orW = 4 or W = 5 or W = 7)=P(W = 3) + P(W = 4) + P(W = 5) +P(W=7)=0.1 + 0.06 + 0.02 + 0.02LisaP(W > 3) = P(W = 4 or W = 5 or W = 7)=P(W = 4) + P(W = 5) +P(W=7)=0.06 + 0.02 + 0.02=0.1 or 10%=0.2 or 20%Therefore, the probability of picking a learnerhaving 3 or more siblings out of 50 students is 0.10or 10% of chance.Therefore, the probability of picking a learner having3 or more siblings out of 50 students is 0.20 or 20%chance.Who do you think got the correct answer?

TRACK/STRAND & SEC.: SCORE: (HOW MANY SIBLINGS DO THE LEARNERS HAVE) In your Statistics class, the teacher wants to know the number of siblings the learners have.
