1. How many outcomes can be obtained by tossing a coin?
a) 1
b) 2
c) 3
d) 4
View Answer
Explanation: A coin has two sides i.e. head and tail. When a coin is tossed, we can get either head or tail. Thus, there are 2 outcomes when a coin is tossed.
2. How many outcomes can be obtained by tossing 2 coins?

b) 2
c) 3
d) 4
View Answer
Explanation: A coin has two sides i.e. head (H) and tail (T). When a coin is tossed, we can get either head or tail. When 2 coins are tossed, the possible outcomes are HH, HT, TH, TT. Thus, there are 4 outcomes when 2 coins are tossed.
3. How many outcomes can be obtained by tossing 3 coins?
a) 1
b) 2
c) 8
d) 4
View Answer
Explanation: A coin has two sides i.e. head (H) and tail (T). When a coin is tossed, we can get either head or tail. When 3 coins are tossed, the possible outcomes are HHH, HHT, HTH, HTT, THH, THT, TTH, TTT. Thus, there are 8 outcomes when 3 coins are tossed.
