A Bag Contains 3 Red Marbles And 5 Purple Marbles

Another marble is taken from the bag.

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. Count the number of favorable outcomes 2 blue 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 marble is taken at random and replaced.

Draws are made without replacement. Thus the probability to draw a red marble is p 2 nd marble is red 3. The problem asks for the probability of rr or bb. What is the probability of picking a blue marble.

You have 15 marbles in total and 7 purple ones. Total number of marbles in the bag is 3 4 7. Work out the probability that the two marbles taken from the bag are the same color. Since you have put the first marble back in the bag you still have 15 marbles in total.

However there are only 3 red ones. A bag contains 5 green marbles 3 yellow and 2 red marbles. A bag contains 3 red marbles and 4 blue marbles. The probability is about 9 33.

What is the probability you choose a red or a green marble. The probability of choosing a card with a number less than 4 is unlikely less than one half. A bag contains 5 red marbles and 4 pink marbles. A bag contains 7 red marbles 3 purple marbles and 2 blue marbles.

What is the probability the first marble is pink and the second is red. There are 8 total in the bag and 5 of them are purple so the probability that the first one is purple is. A box contains 5 purple marbles 3 green marbles and 2 orange marbles. P 1st orange then green answer choices.

Determine if this event is likely or unlikely.
