Find the probability that in a pig family of 4 offspring there will be at least 1 male and 1 female. Assume that the probability
Naya [18.7K]
The probability of there being zero males is given by:
P(zero\ males)=4C0\times0.5^{0}\times0.5^{4}=\frac{1}{16}
Similarly the probability of there being zero females is also 1/16.
The probability there will be at least 1 male and 1 female is therefore:
1-(\frac{1}{16}+\frac{1}{16})=\frac{7}{8}
The answer is: 7/8.

Water flows from a tank with a rectangular base measuring 80cm by 70cm into another tank with a squarebase of side 60cm. If the
defon

Answer:

70cm

Step-by-step explanation:

,

Since, both of the tank posses the same quantity of water then there volume is the same thing

For rectangular base

Volume= (Lenght × breadth × hheight)

If we substitute values

Lenght= 80 cm

Breadth= 70 cm

height= 45 cm

Volume= 80cm × 70cm × 45cm

Volume= 252000cm^3

For square base

Volume= (side)^2 × height

side =60cm.

But volume of square base= volume of

rectangular base

252000cm^3= 60^2 × height

Height= (252000cm^3)/(60^2 )

Height= 70 cm

Hence, the second tank is 70 cm deep
