A bag contains six yellow marbles and seven blue marbles. The marbles are randomly selected one at a time. What the odds in favor of picking the yellow marble on the first selection? to You mix the letters S,E,L,E,C,T,E, and D thoroughly. Without looking, you draw one letter. Find the probability of the event. P(not C) 8 8/7 7/8 1/8 If the spinner is spun twice, what is the probability that the spinner will stop on a vowel THEN a consonant? 1/12 2/9 1/9 1/2 L I U E O Z T T H T H T H T T T H T T H T H=heads 1/3 2/3 5/8 2 T=tails Find the experimental probability of tossing heads. Suppose you spin the spinner. Find the probability. P(red)= REDUCE the FRACTION! R R R R Y B B G P(red or blue) = Suppose you spin the spinner. Find the probability. REDUCE the FRACTION! R R R R Y B B G You mix the letters S,E,M,I,T,R,O,P,I,C,A, and L throughly. Without looking, you draw one letter. Find the probability that you select a consonant.
