The probability of getting tails on one toss of a fair coin is 1/2.
Since each toss is independent of the others, the probability of getting tails 5 times in a row is:
(1/2) x (1/2) x (1/2) x (1/2) x (1/2) = 1/32
Therefore, the probability of tossing 5 tails in a row is 1/32 or approximately 0.03125.

A jar contains 8 red marbles numbered 1-8 and 6 blue marbles numbered 1-6. Marble drawn at random from the jar. Find the probability marble is red
There are a total of 8+6=14 marbles in the jar.
The probability of selecting a red marble is the number of red marbles divided by the total number of marbles:
P(red) = 8/14 = 4/7
Therefore, the probability of drawing a red marble from the jar is 4/7 or approximately 0.57.
The probability of selecting a red marble is the number of red marbles divided by the total number of marbles:
P(red) = 8/14 = 4/7
Therefore, the probability of drawing a red marble from the jar is 4/7 or approximately 0.57.
