If a coin is tossed 5 times what is the probability of getting 5 heads?
If a fair coin is tossed 5 times, the probability of getting 5 heads is:P(H,H,H,H,H) = (1/2)5 = 1/32 = 0.03125 = 3.125% ≈ 3.1%
How many outcomes are there when you flip a coin and roll a die?
12..... h+1, h+2, h+3, h+4, h+5, h+6, t+1, t+2, t+3, t+4, t+5, t+6,
What is probability of throwing 9 heads in a row?
If you toss a coin often enough the probability is 1. The probability of 9 H in the first 9 tosses is (1/2)9 = 1/512
Formula for perimeter of a hexagonal prism?
A hexagonal prism is a polyhedron with two parallel bases bounded by congruent hexagons and with lateral faces bounded by parallelograms that connect corresponding sides of the bases. The height h of the prism is any perpendicular segment drawn from a point on the base to the plane containing the other base. If the segments that join corresponding vertices of the bases are perpendicular to the bases, then the prism is a right hexagonal prism. Otherwise, it is called oblique. The perimeter formula of a right regular hexagonal prism is P = 12s + 6h where s = side and h = height
You are going to toss 2 pennies 20 times how many times do you expect the 2 pennies will come up as 2 heads?
5 times.When tossing 2 pennies there are 4 equiprobable outcomes or events with 1/4 ofprobability for each to happen:P(H,H) = 1/4P(H,T) = 1/4P(T,H) = 1/4P(T,T) = 1/4So if you toss 2 pennies 20 times, the "expected" number of times that 2 heads (H,H)will come up is 1/4 of the 20 times, that is 5 times.
