Answer:
If you take into account all probabilities, and work on a strategy, rather than individual guesses, you can increase the probability.
Here are the possible outcomes:
BBB
BBR
BRB
BRR
RBB
RBR
RRB
RRR
If you use the strategy:
If a person sees a blue and a red, they pass;
If a person sees a blue and a blue, they guess red;
If a person sees a red and a red, they guess blue;
The probability comes out like this:
(B=blue, R=red, P=pass)
actual guess correct?
BBB RRR no
BBR PPR yes
BRB PRP yes
BRR BPP yes
RBB RPP yes
RBR PBP yes
RRB PPB yes
RRR BBB no
As you can see, this is a 6/8, or 75% chance of being correct.
For this case we must factor the following expression:
We manipulate algebraically, taking into account that different signs are subtracted and the sign of the major is placed:
We divide by 3 on both sides of the equation:
To factor, we look for two numbers that, when multiplied, result in -6 and when added, result in -5. These numbers are -6 and +1.
Thus, we factor the equation:
The roots of the equation are:

Step-by-step explanation:
lol look it up bruh
no because if you simplify 0.248 to the nearest hundredth it turns into 0.25 therefore it will be less than 0.29
