Applying the given probabilities, it is found that there is a 0.42 = 42% probability of watching a movie today.

These following <em>probabilities </em>involve a movie being watched today:

  • 0.5 of 0.6(if it rains today).
  • 0.3 of 1 - 0.6 = 0.4(if it does not rain today).

Hence, adding them:

p = 0.5(0.6) + 0.3(0.4) = 0.3 + 0.12 = 0.42

0.42 = 42% probability of watching a movie today.

There are eight students in a class. Only one of them has passed Exam P/1 and only one of them has passed Exam FM/2. No student
Svetach [21]

Answer: There is probability of 0.57 chances that exactly three students from a group of four students have not passed Exam P/1 or Exam FM/2.

Step-by-step explanation:

Total number of students = 8

Number of student who has passed Exam P/1 = 1

Number of student who has passed Exam FM/2 = 1

No student has passed more than one exam.

According to question, exactly three students from a randomly chose group of four students have not passed Exam P/1 or Exam FM/2.

So, Probability will be

\frac{^6C_3\times ^2C_1}{^8C_4}\\\\=\frac{20\times 2}{70}\\\\=\frac{4}{7}\\\\=0.57

Hence, there is probability of 0.57 chances that exactly three students from a group of four students have not passed Exam P/1 or Exam FM/2.

Solve:<br> 2(x+2)-5=3(x-1)
sergejj [24]
Answer:
x = 2

Explanation:
2(x+2)-5=3(x-1)
1) Use distributive property (multiply the 2 by x+2 and the 3 by x-1)
2x+4-5=3x-3
2) Combine like terms
2x-1=3x-3
3) Subtract 2x on both sides
-1=x-3
4) Add 3 on both sides
2=x

hope this helps!
