Answer:

The probability of rolling a 3 and then a 5 is 1/36.

Step-by-step explanation:

Rolling a six sided die is an independent event.  That means for each roll, you have the same chance of rolling a number as the previous roll.  Since there are six different numbers on a die, then there are six different outcomes for each roll - 1, 2, 3, 4, 5 or 6.  The chances that you would roll a '3' is 1 out of 6, or 1/6.  The chances that you would roll a '5' is also 1 out of 6, or 1/5.  However, when we combine these events, we need to take each probability and multiply them.  So, the probability of rolling a '3' and then a '5' is 1/6 x 1/6 or 1/36.

Lunna [17]

Answer:

\huge\boxed{g(a-1)=\dfrac{2-a}{a}=\dfrac{2}{a}-1}

Step-by-step explanation:

g(t)=\dfrac{1-t}{1+t}\\\\g(a-1)-\text{substitute}\ t=a-1\ \text{to}\ g(t):\\\\g(a-1)=\dfrac{1-(a-1)}{1+(a-1)}=\dfrac{1-a-(-1)}{1+a+(-1)}=\dfrac{1-a+1}{1+a-1}=\dfrac{(1+1)-a}{(1-1)+a}=\dfrac{2-a}{a}
