Question

If 4 coins are tossed simultaneously, then the maximum number of outcomes would be ?

• A. 9
• B. 5
• C. 16
• D. 8

Answer 1

The correct option is C 16

A toss of one coin has 2 (i.e., $2^1$) possible outcomes (H and T).
Simultanous toss of two coins has 4 (i.e., $2^2$) possible outcomes (HH, TT, HT and TH).
Simultanous toss of three coins has 8 (i.e., $2^3$) possible outcomes.
Similarly, simultanous toss of four coins has $2^4=16$ possible outcomes.
