Probability of T, T, T, T, T, T or 1/2 * 1/2 * 1/2 * 1/2 * 1/2 * 1/2 or 1/64 or 0.015625.
None the earth has no head! Please correct me if I am wrong...
None, since that would imply that in 18 cases the coin did not show heads or tails!
This is a binomial probability distribution The probability of exactly 2 heads in 50 coin tosses of a fair coin is 1.08801856E-12. If you want to solve this for how many times 50 coin tosses it would take to equal 1 time for it to occur, take the reciprocal, which yields you would have to make 9.191019648E11 tosses of 50 times to get exactly 2 heads (this number is 919,101,964,800 or 919 billion times). If you assume 5 min for 50 tosses and 24 hr/day tossing the coin, it would take 8,743,360 years. That is the statistical analysis. As an engineer, looking at the above analysis, I would say it is almost impossible flipping the coin 50 times to get exactly 2 heads or I would not expect 2 heads on 50 coin tosses. So, to answer your question specifically, I would say none.

None. The full name is the Probability Distribution Function (pdf).
No, none of the members of Talking Heads are dead.
There are no 60p coins, so the answer is none.
For a normal deck of cards, the answer is none.
None of the digits can be 10, so the probability is 0.
The number of trials: n = 9, the number of success: r = 4. The probability of success: P(H) = 1/2, the probability of failure: P(T) = 1/2. P(exactly 4 heads in 9 tosses) = 9C4 x (1/2)^5 x (1/2)^4 = 126(1/2)^9 = 0.246 P(at most 2 heads) = P(none heads) + P( 1 head) + P(2 heads) = 9C0[(1/2)^9][(1/2)^0] + 9C1[(1/2)^8][(1/2)^1] + 9C2[(1/2)^7][(1/2)^2] = 1(1/2)^9 + 9(1/2)^9 + 36(1/2)^9 = (1 + 9 + 36)(1/2)^9 = 46(1/2)^9 = 0.09
None, if you do not have the necessary qualifications.
None. There are no coins in a dollar. A dollar is a paper bill.
