Answer:
0.06
Step-by-step explanation:
probability of multiple of 6= 0.2
probability of multiple of 4= 0.3
0.2 * 0.3 = 0.06
Some textbooks describe direct variation by saying " y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x . ") This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.
We need to correctly choose exactly 4 out of the 6 drawn numbers.
Apply hypergeometric distribution:
a=number of correctly chosen numbers = 4
A=number of correct (drawn) numbers = 6
b=number of incorrectly chosen numbers = 2
B=number of undrawn numbers = 44-6 = 38
Then by the hypergeometric distribution
P(a,b,A,B)
=C(A,a)C(B,b)/C(A+B,a+b) [C(n,r)=combination of r objects taken out of n]
=C(6,4)C(38,2)/C(44,6)
=15*703/7059052
= 10545/7059052
= 0.001494 (to the nearest millionth)
Answer: probability of winning third prize is 10545/7059052=0.001494
I see 3 right triangles.
Right triangle: a² + b² = c²
a = long leg ; b = short leg ; c = hypotenuse
hypotenuse = EH
a = 6 - 3 = 3
b = 3 - 1 = 2
c² = 3² + 2²
c² = 9 + 4
c² = 11
c = √11
c = 3.32
hypotenuse = FG
a = 3 ; b = 1
c² = 3² + 1²
c² = 9 + 1
c² = 10
c = √10
c = 3.16
hypotenuse = EF
a = 3 ; b = 2
c² = 3² + 2²
c² = 9 + 4
c² = 11
c = √11
c = 3.32
perimeter = 3.32 + 3.16 + 3.32 + 2 = 11.8
