Answer:

687.5 \:  {ft}^{2}

Step-by-step explanation:

Area of polygon = Area of square + Area of triangle

=  {25}^{2}   + \frac{1}{2}  \times 25 \times (30 - 25) \\  \\  = 625 +\frac{1}{2}  \times 25 \times5 \\  \\  = 625 +  \frac{1}{2}  \times 125  \\  \\  = 625 + 62.5 \\  \\  = 687.5 \:  {ft}^{2}

A pair of dice is rolled, and the sum of the numbers is either 7 or 11. What is the probability of this event?
AfilCa [17]

Answer:   \dfrac{2}{9}

Step-by-step explanation:

Let A be the event that the sum is 7 and and B be the event that the sum is 11 .

When two pair of dices rolled the total number of outcomes = n(S)=6\times6=36

The sample space of event A ={(1,6), (6,1), (5,2), (2,5), (4,3), (3,4)}

Thus n(A)= 6

The sample space of event B = {(5,6), (6,5)}

n(B)=2

Since , both the events are independent , then the required probability is given by :-

P(A\cup B)=P(A)+P(B)\\\\=\dfrac{n(A)}{n(S)}+\dfrac{n(B)}{n(S)}=\dfrac{6}{36}+\dfrac{2}{36}=\dfrac{8}{36}=\dfrac{2}{9}

Hence, the required probability = \dfrac{2}{9}
