Let A = {15, 25, 35, 45, 55, 65} and B = {25, 45, 65}. What is A _ B? can someone please help me

VARVARA [1.3K]

The operation indicated, A - B, is a subtraction of sets.

The subtraction of set B from set A means that you have to remove the elements of B that are on A; i.e. A - B = {15, 35, 55}

25, 45 and 65 (which are in the set B) were removed from the set A to form the set A - B

50% of babies are born female Oliver wants to find the probability that 20 or more of the 50 babies born today were female if we

jarptica [38.1K]

Solution:

Number of babies which are female = 50%= $\frac{1}{2}$

So, if Population of 50 is considered , and 50% of population is female then out of 25 must be female.

Population of female can't exceed 25.

Probability of an event = $\frac{\text{Total favorable outcome}}{\text{Total Possible outcome}}$

Probability that 20 or more of the 50 babies born today were female

= $_{20}^{50}\textrm{C}\times [\frac{1}{2}]^{20} \times [\frac{1}{2}]^{30}+_{21}^{50}\textrm{C}\times [\frac{1}{2}]^{21} \times [\frac{1}{2}]^{29}+_{22}^{50}\textrm{C}\times [\frac{1}{2}]^{22} \times [\frac{1}{2}]^{28}+_{23}^{50}\textrm{C}\times [\frac{1}{2}]^{23} \times [\frac{1}{2}]^{27}+_{24}^{50}\textrm{C}\times [\frac{1}{2}]^{24} \times [\frac{1}{2}]^{26}+ _{25}^{50}\textrm{C}\times [\frac{1}{2}]^{25} \times [\frac{1}{2}]^{25}$

Simulation of the Above Situation

If we use a double sided coin and a sign heads us females and Tails as males,Toss the coin 50 times , number of times Heads comes shows number of females born and number of times tails appears shows Population of men.

It may not happen that Number of heads =Number of tails if we toss the coin 50 times.So if number of tosses increases the chances are more likely that , number of heads= Number of tails. But for above problem we just have to toss coin 50 times only, that is

Number of males = Number of females

The distance light travels in one second (one light second ) - 1.86 x 10^5 miles
Saturn is 475 light seconds away from the sun. Using this information we are asked to find the distance saturn is away from the sun.
1 light second - 1.86 x 10^5 miles
Therefore 475 light seconds -1.86 x 10^5 miles/light second * 475 light seconds
= 8.83 x 10^7 miles
Saturn is 8.83 x 10^7 miles away from the sun
