=> 10 – u
Step-by-step explanation:
Algebraic expression is the expression that contains the combination of number, variables and operators like addition, division, subtraction and multiplication.
The probability is 5/9.
The probability that he teleports at least once per day is the same as 1 - (probability he doesn't teleport). The probability that he doesn't teleport in the morning is 2/3; in the evening it is 2/3. This means the probability he doesn't teleport at all that day is (2/3)(2/3) = 4/9. The probability he teleports at least once that day, then, is 1-4/9 = 5/9.
