Suppose you roll a standard number cube once. Are rolling a 4 and rolling a 3 mutually exclusive events? Explain.

1 answer:

3 0

Yes, they are. They cannot happen both. Every time that you roll a cube you can get only one number, then if you roll a 4 you cannot roll a 3 at the same tiem, and if you roll a 3 you cannot roll a 4 at the same time.

Mutually exclusive events cannot happen at the same time.

Answer:

10.77 units

Step-by-step explanation:

By imaging an imaginery line at point before 1 units to be 4 units: b = 4 units

Therefore h = 11 - 1 = 10 units

Using Pythagoras theorem:

x² = h² + b² = 10² + 4² = 100 + 16 = 116

x = √116 = 10.77 units
