Final answer:

The probability P(A), where event A is the first die landing on a 5 when rolling a pair of dice, is 1/6.

Step-by-step explanation:

Calculating the probability of the first die landing on 5 in a dice roll

Here's how to calculate the probability that the first die lands on 5:

Identify the relevant event: Event A represents the first die landing on 5.

Count the favorable outcomes: Out of the 36 possible outcomes listed in the sample space (assuming it's not provided here), only 6 of them have the first die showing 5. These are:

(5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6)

Calculate the probability: Divide the number of favorable outcomes by the total number of possible outcomes:

P(A) = Number of favorable outcomes / Total number of outcomes

P(A) = 6 / 36 = 1 / 6

Therefore, the probability that the first die lands on 5 is 1/6.

Answer:

P(A)=1/6

Step-by-step explanation:

The sample space of the two dice is given below:

[1, 1], [1, 2], [1, 3], [1, 4], [1, 5], [1, 6]

[2, 1], [2, 2], [2, 3], [2, 4], [2, 5], [2, 6]

[3, 1], [3, 2], [3, 3], [3, 4], [3, 5], [3, 6]

[4, 1], [4, 2], [4, 3], [4, 4], [4, 5], [4, 6]

[5, 1], [5, 2], [5, 3], [5, 4], [5, 5], [5, 6]

[6, 1], [6, 2], [6, 3], [6, 4], [6, 5], [6, 6]

n(S)=36

Let A be the event that the first die lands on 5

Sample Space of Event A is:

[5, 1], [5, 2], [5, 3], [5, 4], [5, 5], [5, 6]

n(A)=6

Therefore:

P(A)=n(A)/n(S)

=6/36

=1/6
