P(5 or 8) = \frac{2}{12} = \frac{1}{6} or 16.666%.

Step-by-step explanation:

Step 1; To determine the chances of a particular event to occur, we divide the number of outcomes that are favorable by the number of possible outcomes. In this case, the favorable outcomes are those which have both 5 and 8 in their 2 digit number and the number of outcomes is a count of all the ways in which the four numbers 6, 5, 1 and 8 can be used to form any two-digit numbers.

Step 2; From the tree diagram, we infer that there are two numbers that can be formed with both 5 and 8 i.e. 58 and 85. The total number of possible outcomes is 12 i.e. 65, 61, 68, 56, 56, 58, 16, 15, 18, 86, 85 and 81.

So P(5 or 8) = \frac{numberof favorableoutcomes}{total number of outcomes} = \frac{2}{12} = \frac{1}{6} = 0.1666 × 100 = 16.66%.

Nastasia [14]

Answer:

EB = |1 – (− 5)| = 6

AE = |4 – (− 4)| = 8

Using the Pythagorean Theorem to find AB:

AB2  =  EB2 + AE2

AB2  =   62 + 82

AB2  =  36 + 64

AB  =  \sqrt{100}

AB  =  10
