For a fair coin,
Probability of a head, P(H) = 1/2 = 0.5
Probability of a tail , P(T) = 1/2 = 0.5
The number of possible outcomes is small enough to simply list the outcome:
The possible outcomes of flipping a coin 7 times and getting heads 6 times are these 7 possibilities:
THHHHHH
HTHHHHH
HHTHHHH
HHHTHHH
HHHHTHH
HHHHHTH
HHHHHHT
The probability of EACH of the above outcomes is
= (0.5)(0.5)(0.5)(0.5)(0.5)(0.5)(0.5)
= (0.5)⁷
Since there are 7 possibilities and since the probabilities of every outcome is identical, the probability of rolling the 7 outcomes is,
= 7 x probability of each outcome
= 7 x (0.5)⁷
= 0.5468
= 5.468%
= 5.5% (nearest tenth)

Answer:
1. x<3
2. x<3
Step-by-step explanation:
2x-5<1
Move constant to the right side and change its sign
2x<1+5
Add the Numbers
2x<6
Divide both sides of the inequality by 2
x<3
3x+7<16
Move constant to the right side and change its sign
3x<16-7
Subtract the numbers
3x<9
Divide both sides of the inequality by 3
x<3
