Answer:
answer: 189
Step-by-step explanation:
Formula to find triangles area is base x height ÷ 2 So... 7 x 10 = 70 70 ÷ 2 = 35 Now sense we have 4 identicle triangles we will just do 35 × 4 amd 35 × 4 = 140 now for the square its simply just base x height so 7 × 7 = 49 now we will add these up...140 + 49 = 189 so 189 is the area. Hope this helps!

Answer:
Event A = white marble is selected
Event B = blue marble is selected
P(A) = 5/10 = 1/2
p(B) = 5/10 = 1/2
Probability that A and B are independent events is:
P(A∩B) = 1/2 × 1/2
Answer: 1/4
