The following table shows whether students dominant hand was their right hand or not and which of their feet were longer. If a student’s left foot was longer, there is an L; right foot is longer, R; or if their feet are the same size, S. If a student’s dominant hand is the right hand, there is an H; and if it is not, HHCC. In A - J you may leave as fractions or round to 3 decimal places as needed. A. Find PP(RR) B. Find P(H) C. Find P(HHCC) D. Interpret what P(HHCC) means in practical terms, in the context of this
The following table shows whether students dominant hand was their right hand or not and which of their
feet were longer. If a student’s left foot was longer, there is an L; right foot is longer, R; or if their feet are
the same size, S. If a student’s dominant hand is the right hand, there is an H; and if it is not, HHCC. In A - J
you may leave as fractions or round to 3 decimal places as needed.
A. Find PP(RR) B. Find P(H) C. Find P(HHCC)
D. Interpret what P(HHCC) means in practical terms, in the context of this problem. Write a sentence.
E. Find PP(HH ∩ RR)
F. Find PP(HH ∪ RR)
G. Find P(RR|HH). (In other words, if we know someone is right-handed, what is the likelihood that their
right foot is longer than their left foot?) Show a little work.
H. Find P(HH|RR). (In other words, if we know a person’s right foot is longer than their left, what is the
probability that they are right-handed?)
I. Continue referring to previous page. Are the
probability, then explain what this means in practical terms, in the context of the problem.
J. Are the events H and RR independent or dependent? Show with a probability, then explain what this
means in practical terms, in the context of the problem.
