Probability Calculation Given that a box has 4 blue marbles, 3 red marbles, and 5 yellow marbles, use the probability formulas to answer the following questions. Reduce all fractions. Use f as the fraction bar and do not use any spaces. What is the probability of... 1. Drawing a blue marble? P( B )= ya 0 2. Drawing a marble that is not red? o P( R' )= 3/4 3. Drawing a red and yellow marble at once? P( RnY: )= EMS 4. Drawing a red or blue marble. P( RUB: )= 7:12 5. Drawing a red marble, put it back, and then drawing a yellow marble? P( )= 0 6. Drawing a yellow marble, keeping it, and then drawing another yellow marble? P( o )= 7. Drawing a yellow marble, given that a red marble was drawn on the first draw and not replaced? P( o V II
