What is the probability that Fatima gets fewer heads than tails if she flips 10 coins?
If 10 coins are tossed, you could get 4 heads and 6 tails, 3 heads and 7 tails, 2 heads and 1 tail, 0 heads and 10 tails all giving fewer heads than tails.
Using the binomial distribution ,
P(4 heads) = 10C4 (.5)^4 (.5)^6 = 0.205078.
P(3 heads) = 10C3 (.5)^3 (.5)^7 = 0.117188
P(2 heads) = 10C2 (.5)^2 (.5)^8 = 0.043945
P(1 heads) = 10C1 (.5)^1 (.5)^9 = 0.009766
P(0 heads) =(.5)^10 = 0.000977
Adding all of these probabilities, we have P(fewer heads than tails)= 0.376953

What is the probability of two consecutive different coin flips?
The probability is 1/2 if the coin is flipped only twice. As the number of flips increases, the probability approaches 1.
What is the probability of flipping a head when you roll a coin 3 times?

What is the probability of obtaining exactly six heads in seven flips of a coin given that at least one is a head?
The requirement that one coin is a head is superfluous and does not matter. The simplified question is "what is the probability of obtaining exactly six heads in seven flips of a coin?"... There are 128 permutations (27) of seven coins, or seven flips of one coin. Of these, there are seven permutations where there are exactly six heads, i.e. where there is only one tail. The probability, then, of tossing six heads in seven coin tosses is 7 in 128, or 0.0546875.
When tossing 2 coins the probability of getting exactly 1 tail is one over 3?
No, the possible results of two coin flips are; HH HT TH TT The probability of getting exactly one tail is 1/2 or 50%.
You toss three coins What is the probability of the event 3 Heads appear?
Since each event is independent (heads in one coin does not affect the probability of the other two coin flips), the multiplication rule applies: 1/2 x 1/2 x 1/2 = 1/8 or 0.125. So we can say the probability is 12.5%.
What is the probability that the first two flips will both be heads and the third flip will be tails if you flip three fair coins?
To find the probability of getting heads on the first two flips and tails on the third flip when flipping three fair coins, we multiply the probabilities of each individual event. The probability of getting heads on a flip is 1/2, so for the first two flips, it is (1/2) * (1/2) = 1/4. The probability of getting tails on the third flip is also 1/2. Therefore, the overall probability is (1/4) * (1/2) = 1/8.
What is the probability of flipping 1 head out of five coins?
The probability of HTTTT is (1/2)5 = 1/32 The correct flips can also be achieved with THTTT, TTHTT, TTTHT, & TTTTH. Hence, total probability is 5/32.

If You flip 9 fair coins Amazingly the first 8 flips all come up heads What is the probability that the final flip will be a head too?
1/2 apex It does not matter what each prior flip's result was. Each flip has a probability of 0.5 heads or tails. Coins do not have "memory".
What is the probability of tossing seven coins and getting 6 heads?
The probability of getting only one tails is (1/2)7. With seven permutations of which flip is the tails, this gives a probability of: P(six heads in seven flips) = 7*(1/2)7 = 7/128
