total outcome in single toss={H,T}
u want 1 head
probability of getting 1 head= 1/2=0.5
The probability of tossing a coin and getting heads is 0.5
If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8
Probability of getting a head or tail is not equal
To find the probability of getting at least one head in 4 coin tosses, it's easier to calculate the complementary probability of getting no heads at all (i.e., getting all tails). The probability of getting tails in a single toss is 0.5, so for 4 tosses, the probability of all tails is ( (0.5)^4 = 0.0625 ). Therefore, the probability of getting at least one head is ( 1 - 0.0625 = 0.9375 ) or 93.75%.
the probability of getting one head and one tail on three flips of a coin is 1/9
0.63 = 0.216
Assuming that it is a fair coin, the probability is 0.9990
0.5, if the coin is fair.
The probability is 50-50.
The probability is 0.998
The probability is 1/4
on one coin, the probability of getting a head is 0.5, if there is no bias
