Answer:
0.25
Step-by-step explanation:
You divide the denominator (bottom) into the numerator (top).
1/4 = 1 / 4.00 = 0.25
X takes values: { 3, 4, 5 }
where: P ( X = 3 ) + P ( X = 4 ) + P ( X = 5 ) = 1
For X = 3 we have : BBB or GGG.
P ( X = 3 ) = ( 1/2 * 1/2 * 1/2 ) * 2 = 1/8 * 2 = 2 / 8 = 1/4
P ( X = 4 ) = ( 1/2 * 1/2 * 1/2 * 1/2 ) * 6 = 6 /16 = 3/8
P ( X = 5 ) = ( 1/2 * 1/2 * 1/2 * 1/2 * 1/2 ) * 12 = 12 / 32 = 3/8
1 / 4 + 3 / 8 + 3 / 8 = 8 / 8 = 1
Answer:
2 gram/milliliter or 2000 kilogram/cubic meter
Step-by-step explanation:
ρ =
m/
V
= 10 gram/ 5.0 milliliter
= 2 gram/milliliter
= 2000 kilogram/cubic meter
