Step-by-step explanation:
The given expression is 26.48. We need to write the equivalent expression for it. There are two numbers after decimal. It means that we can divide 2648 by 100 i.e.
We know that, 2648 = 662 × 4 and 100 = 25 × 4
Hence, is the equivalent expression.
If two events are disjoint (i.e. mutually exclusive) they cannot both occur and so we can determine probabilties by simple addition:
A more complete answer would use a joint probability table but that's difficult to type out/format correctly here.
