Answer:
Step-by-step explanation:
there are 36 squares
red takes 1 of 4 so red has 9
blue takes 1 of 3 so blue has 12
5 of 12 of the grid is yellow
The probability of rolling an even number is three times (2,4,6) and the probability of rolling a number less than 5 is 4 times (1,2,3,4)
Not sure if I'm right or not but I hope this helps :)
Answer:
x=6
Step-by-step explanation:
4x-1=2x+11
4x-2x-1=11
2x-1=11
2x=11+1
2x=12
x=12/2
x=6
Answer: 0.2401
Step-by-step explanation:
The binomial distribution formula is given by :-
![P(x)=^nC_xp^x(1-p)^{n-x}](https://tex.z-dn.net/?f=P%28x%29%3D%5EnC_xp%5Ex%281-p%29%5E%7Bn-x%7D)
where P(x) is the probability of x successes out of n trials, p is the probability of success on a particular trial.
Given : The probability that a randomly chosen citizen-entity of Cygnus is of pension age† is approximately: p =0.7.
Number of trials : n= 4
Now, the required probability will be :
![P(x=4)=^4C_4(0.7)^4(1-0.7)^{4-4}\\\\=(1)(0.7)^4(1)=0.2401](https://tex.z-dn.net/?f=P%28x%3D4%29%3D%5E4C_4%280.7%29%5E4%281-0.7%29%5E%7B4-4%7D%5C%5C%5C%5C%3D%281%29%280.7%29%5E4%281%29%3D0.2401)
Thus, the probability that, in a randomly selected sample of four citizen-entities, all of them are of pension age =0.2401
