Expected number of tosses of a fair coin to get 3 consecutive heads.

• The probability of getting 3 consecutive heads is 1/8

• The expected number of tosses to get 3 consecutive heads is 14

• This can be calculated using the formula E(X) = 2^k + 2^(k-1) + 2^(k-2) + ... + 2^2 + 2^1 + 2^0, where k is the number of consecutive heads required

Go second. The probability of winning is higher when going second.

• The probability of winning when going first is (1/n+1), while the probability of winning when going second is (n/n+1)

• This is because the first player has a chance of drawing the black ball on their turn, while the second player has a chance of drawing the black ball on their turn or the first player's turn

• For example, if there are 10 red balls and 1 blac...read more

Probability of a randomly dropped rod of length L intersecting a line on a 2D plane with infinite parallel, vertical lines.

• The probability depends on the length of the rod L.

• The probability can be calculated using geometric probability.

• For example, if L = 1, the probability is 0.5.

• If L = 2, the probability is 0.75.
