Question

A single, six-sided die is rolled. Find the probability of rolling an odd number or a number less than 4. The probability is _____.

Answer 1

2/3

Explanation:

The sample space of the die would be: {1, 2, 3, 4, 5, 6}

The sample space of the odd numbers would be: {1, 3, 5}

The sample space of numbers less than 4: {1, 2, 3}

Now, if we combine these last two sample spaces, we would have the following: {1, 2, 3, 5}

Therefore, we have 4 possibilities within these restrictions and in total there are 6, therefore, the probability would be:

`p=(4)/(6)=(2)/(3)`

The probability is 2/3
