Suppose you toss a fair, two-sided coin.

List the sample space.
List one possible event.
Calculate the probability of that event.

Step-by-step explanation:

Suppose you toss a fair coin having two sides head and tail.

The sample space s = {H,T}

One of the possible events occur will be head ( or tail)

The probability of that event will be 50% because the tossed coin either shows the head or tail.

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
