Answer:
Option 1
Step-by-step explanation:
P(glasses' ^ internet) = 3/20 = 0.15
P(glassses') = 8/20 = 0.40
P(internet) = 7/20 = 0.35
(0.40×0.35) = 0.14
Answer:
No
Step-by-step explanation:
It will be a right triangle if it follows Pyhthagoras Theorem . Where the sum of squares of two smaller sides is equal to the square of the 3rd side. Let's check ,
→ 11²+ 12² = 13²
→ 121 + 144 = 169
→ 265 ≠ 169
<h3>Hence the ∆ is not a right angled triangle </h3>
