The equation y= 2 has one real root and that is x=-1.
What is real roots of the equation?
We are aware that when we resolve a linear or quadratic equation, we always arrive at the value variable of the equation, or, to put it another way, we always locate the equation's solution. This "solution" is what we refer to as the real roots. For instance, when the equation -7x+12=0 is solved, the actual roots are 3 and 4.
Here given,
=> y = 2
Take y=0 then,
=> 2=0
=> =0
=>(x+1)=0
=> x=-1
Hence the given equation has one real root and that is x=-1.

We know that in a standard deck of 52 cards there are 4 suits and each suit has one card with the number 8. Thus, 4 suits will have 4 cards with the number 8. Therefore, the total number of events in the sample space is 52 and the total number of favorable events is 4.
Thus, if a card is drawn from a standard deck of 52 cards, the theoretical probability of drawing a number 8 is given by:
Thus, round the decimal to the nearest hundredth, the theoretical probability of drawing a number 8 from a standard deck of 52 cards is given by 0.08.
