Question

Let S = { 1, 2, 3, 4, 5, 6 } be the sample space of rolling a die. What is the probability of (a) rolling a 5 ? (b) rolling a number less than one ? (c) rolling a number greater than 0 ? (d) rolling a multiple of 3 ? (e) rolling a number greater than or equal to 4 ?please solve it ​

Answer 1

Answer:

let both equation be 1st and 2nd

now, subtract 2nd from 1st equation, we have

Step-by-step explanation:

2x-5y+4=0

2x+y - 8 =0

- - +

--------------------

0 - 6y+12=0

now ,

6y=12

y=2

hence y =2.

put the vaule of y =2 in 1st eqn. then

2x=6

x=3

Hence y=2and x=3 is answer
