A Bag Contains 3 Red Marbles And 5 Purple Marbles

Once you have chosen the first marble there are only 7 left in the bag since we are doing this without replacement so the probability that the second marble is red given that there are 3 red marbles remaining in the bag is.

A bag contains 3 red marbles and 5 purple marbles.

Thus the probability for the first marble to be purple is p 1 st marble is purple 7 15. What is the probability of picking a blue marble. What is the probability the first marble is pink and the second is red. You have 15 marbles in total and 7 purple ones.

There are 8 total in the bag and 5 of them are purple so the probability that the first one is purple is. Since you have put the first marble back in the bag you still have 15 marbles in total. The probability is about 9 33. A bag contains 5 green marbles 3 yellow and 2 red marbles.

There is a bag of marbles 10 are red 15 are purple and 25 are yellow what is the probability of picking a purple marble. A marble is taken at random and replaced. Total number of marbles in the bag is 3 4 7. However there are only 3 red ones.

A bag contains 5 red marbles and 4 pink marbles. P 1st orange then green answer choices. A marble is randomly drawn and then replaced. Determine if this event is likely or unlikely.

A box contains 5 purple marbles 3 green marbles and 2 orange marbles. Another marble is taken from the bag. Draws are made without replacement. The probability of choosing a card with a number less than 4 is unlikely less than one half.

Thus the probability to draw a red marble is p 2 nd marble is red 3. Work out the probability that the two marbles taken from the bag are the same color. Count the number of favorable outcomes 2 blue marbles. What is the probability you choose a red or a green marble.

The problem asks for the probability of rr or bb.
