Answer:

P(E\ or\ F) = 0.60

Step-by-step explanation:

Given

P(E) = 0.25

P(F) = 0.40

P(E\ and\ F) = 0.05

Required

Determine P(E or F)

This is calculated using:

P(E\ or\ F) = P(E) + P(F) - P(E\ and\ F)

P(E\ or\ F) = 0.25 + 0.40 - 0.05

P(E\ or\ F) = 0.60

Answer:

5x - 63 = 6

Step-by-step explanation:

Okay, first step, let's get all fractions having a common denominator, to do this, multiply 2/3 by 3 to get 6/9. Now, we have 5/9x-7=6/9. To make these into whole numbers, we can multiply the whole equation by the denominator (9). 5/9x multiplied by 9 is 5. 7 multiplied by 9 is 63. 6/9 multiplied by 9 is 6. Now we have 5x-63=6. If I were to simplify the equation, it would require decimals, so I'll leave it at this, but the equation simplified is x=13.8.
