What is the theoretical probability of spinning a 3 and picking an a?
There is insufficient information in the question to properly answer it. You did not specify how many places and how many 3's there are on the spinner, and you did not specify the set from which you could pick an "a", both of which are necessary pieces of information to calculate probability. Please restate the question.
What is the probability that you get a multiple of 2 on both number cube and spinner?
Spinners have different numbers of sides. Moreover, the sides are not necessarily all equal nor that they are numbered in any particular fashion. The answer depends on these factor. They have not been specified and so the question cannot be answered.
There are 4 red marbles and 6 blue marbles in a bag. if Sarah pulls out one marble then another what is the probability that both marbles in her hand will be red?
The probability is 2/15.
What do experimental probability and theoretical probability have in common?
They are both measures of probability.
If A box contains 4 blue chips and 5 black chips and 2 chips are drawn at random with replacement what is the probability that both will be blue?
Two out of nine. 2:9.
If a box contains three blue cards and three white cards If two cards are drawn one at a time find the probability that both cards are blue if the draws are made with replacement?
The probability of drawing two blue cards froma box with 3 blue cards and 3 white cards, with replacement, is 1 in 4, or 0.25.The probability of drawing one blue card is 0.5, so the probability of drawing two is 0.5 squared, or 0.25.

A bag contains 3 blue discs and 5 red discs A disc is the drawn and replacedThen a second disc is drawn Find the probability that both discs are blue?
3/8
A deck of cards has 3 blue 4 black and 6 purple You pick 2 cards from the deck cards are not returned to the deck after they are picked whats the probability that two blue are picked?
First you have 3 blues out of 13 cards, so the first card has probability 3/13. Then you have 2 blues out of 12 cards, so the second card has probability 2/12 or 1/6. The probability of both being blue is the product of these probabilities: P(two blues) = P(first blue) * P(second blue) = (3/13) * (1/6) = 3/78 or 1/26
2 blue marbles and 2 green marbles and 4 blue marbles and 5 green A marble is randomly drawn from each bag What is the probability that both marbles are blue?
it is 6/9 simplifyyou get 2/3.
What is the probability that you will spin a 4 and roll a 4?
Assuming each possible number on a spinner has the same probability and an unbiased die is being rolled, the answer depends on how many numbers are on the spinner, and how many times the number 4 appears on each.To find the probability, workout the probability of spinning a 4 on the spinner and the probability of rolling a 4 on the die; then as spinning the spinner has no effect on rolling the die, they are independent events and to get the probability of both happening multiply them together.The probability of success is the number of successful outcomes divided by the total number of outcomes, giving:Probability(spinning a 4) = how_many_4s_are_on_the_spinner / how_many_numbers_are_on_the_spinnerProbability(rolling a 4) = how_many_4s_are_on_the_die / how_many_numbers_are_on_the_dieProbability(spinning a 4 and rolling a 4) = Probability(spinning a 4) × Probability(rolling a 4)Examples:an octagonal spinner with the numbers 1-4 on it each twice and a tetrahedral die (as used in D&D games) with the numbers 1-4 on it→ pr(spin 4 & roll 4) = 2/8 × 1/4 = 1/16a decagonal spinner with the numbers 0-9 and a tetrahedral die with the numbers 0-3 on it→ pr(spin 4 & roll 4) = 1/10 × 0/4 = 0a decagonal spinner with the numbers 0-9 and a standard die with the numbers 1-6 on it→ pr(spin 4 & roll 4) = 1/10 × 1/6 =1/60
If two events are independent the probability that both occur is?
That probability is the product of the probabilities of the two individual events; for example, if event A has a probability of 50% and event B has a probability of 10%, the probability that both events will happen is 50% x 10% = 5%.
The probability that Bob will win a game of snooker is 0.7 and the probability that he will win a game of chess is 0.6 What is the probability that he will not win both games?
The probability that he will not win both games is 0.58
