Answer:
a) 1/6
b) 1/36
c) 1/720
d) 1/3
Step-by-step explanation:
a) Any of the six comics can perform in the fourth place, so there is one chance in six that Comic F is the one that performs fourth.
![P(F=4th)=1/6](https://tex.z-dn.net/?f=P%28F%3D4th%29%3D1%2F6)
b) In this case, we have two conditions. Both are independent of each other, so the probability of both happening is the product of the probabilities of each happening individually:
![P(D=4th \&B=2nd)=P(D=4th)\cdot P(B=2nd)=(1/6)\cdot(1/6)=1/36](https://tex.z-dn.net/?f=P%28D%3D4th%20%5C%26B%3D2nd%29%3DP%28D%3D4th%29%5Ccdot%20P%28B%3D2nd%29%3D%281%2F6%29%5Ccdot%281%2F6%29%3D1%2F36)
c) This combination is one in all possible orders of perform. The amount of combinations of orders is n!=6!=720 possible combinations. So the probability of this specific order is:
![P(F, D, B, A, C, E)=1/720](https://tex.z-dn.net/?f=P%28F%2C%20D%2C%20B%2C%20A%2C%20C%2C%20E%29%3D1%2F720)
d) In this case, of the six possible comics performing in the last place, we calculate the probability of 2 of them being in that place. So the probability is:
![P(C=6th\,or\, E=6th)=2/6=1/3](https://tex.z-dn.net/?f=P%28C%3D6th%5C%2Cor%5C%2C%20E%3D6th%29%3D2%2F6%3D1%2F3)
23(3) + 3
= 72
Why do you write 2 equations?
Answer:
15 cards.
Step-by-step explanation:
Because 70-15=60. 60 divide by 4 would be 15.
Answer:
um so this is kinda hard not going to lie but here i think its like whatever is n than add and then subtracts it so yes
Step-by-step explanation:
Length of the outer frame: 4+2x
width of the outer frame: 3+2x
area of the outframe: (4+2x)(3+2x)=15
expand the equation: 12+8x+6x+12x^2=15
combine like terms: 4x^2+14x-3=0
