1. The population. Consider tossing 4 coins (HHHH, HTTT, THTT. TTHT, TTTH, HHTT, HTHT, HTTH, THHT, THTH, TTHH, HHHT, HTHH, HHTH, THHH, TTTT) Let Y as the random variable of the number of HEADS when tossing 4 coins Y has a distribution with the number of trials n= and the probability of success p= a) Build a probability distribution table for Y. Find probabilities by formulas P(Y = k) = nck p" (1 - p)"-k OR you can use the TI function "binompdf (n, p, k)" y P(Y=y)
