- Please give answer a,b,c,dList all the possible outcomes from flipping a coin twice and spinning a spinner with three sections labeled red, yellow, and blue. {HHr, HHy, HHb, HTr, HTy, HTb, THr, THy, THb, TTr, TTy, TTb} {HH1, HH2, HH3, HH4, HT1, HT2, HT3, HT4, TH1, TH2, TH3, TH4T, TT1, TT2, TT3, TT4} {HHr, HHy, HHb, HTr, HTy, HTb, THr, THy, THb} {HH1, HH2, HH3, HT1, HT2, HT3, TH1, TH2, TH3, TT1, TT2, TT3}Inside a bag there are 3 green balls, 2 red balls and 4 yellow balls. Two balls are randomly drawn without replacement. Calculate the probability of drawing one red ball and one green ball. The tree diagram has been started.
- A couple has 3 children. Write out the sample space of genders for their children in order of birth, and find the probability that they have exactly 2 boys. (Assume that boys and girls are equallylikely.)Draw a diagram to represent all outcomes when: 3 coins are tossed together (XXX or _, _, _ as results on all 3 coins).Let be a lot of 20 defective items and 80 non-defective items, of which 2 are chosen without replacement. Find the probability that the second item chosen is defective.
- Let A and B be two events with P(A and Bc) = 1. Find P(B). Recall that Bc denotes the complement of the event B.An experiment consists of rolling a pair of fair dice, one red and one green. An outcome is an ordered pair (r,g), where r is the number on the red die and g is the number on the green die. List all outcomes of this experiment.Inside a bag there are 5 green balls, 3 red balls and 2 yellow balls. Two balls are randomly drawn without replacement. Calculate the probability of drawing one green ball and one red ball. The tree diagram has been started.
