Afair coin is tossed three times in succession. the sample space is shown, where h represents avhaed and t represents a tail. find the probability of getting exactly one head

Because the probability of getting heads is 1/2, in a scenario in which it is tossed 3 times, the probability of getting exactly one head is 1/3.

Find 2 numbers multiply those 2 numbers the answer will be -30 but if add them together will get 7so 10 and -3 are the two numbers10(-3) = -3010+(-3) = 7(x-3)(x+10) hope this !

The solution to the system of equations (-2,2)
