The sample space is 22 words and out of it, 14 words are known to have meanings for the student. In the problem, we use 10 C8 + 10 C9 + 10 C10 to associate at least 8 words. The complete formula is (10 C8 * (14/22)^8 * (8/22)^2 + 10 C9 (14/22)^9 * (8/22)^1 + 10 C 10 (14/22)^10 * (8/22)^)0) that is equal to 0.233
Answer:
Problem 1) 
Problem 2) 
Step-by-step explanation:
Problem 1) M(9,6), N(1,4)
Problem 2) M(-2,2), N(4,-4)
The answer would be 6/9
explanation:
2/3 ?/9
if you multiply 3 and 3, it gives you 9, which is the denominator. then you also have to multiply the numerator by the same thing you multiply the denominator with. therefore, 2x3 would give you 6, which makes your answer:
6/9
