Question

Please provide answer with proper solution​

Answer 1

We need to know the favourable cases and the new sample space

No. Of pairs has to counted

(5,1,1) (5,1,2)............(5,1,6)

(5,2,1) (5,2,2)............(5,2,6)

.

.

.

..........................(5,6,6)

6×6=36 cases

Now considering series of 1

(1,1,1) (1,1,2).............(1,1,5) (1,1,6)

(1,2,5)

(1,3,5)

(1,4,5)

(1,5,1)(1,5,2)(1,5,3)(1,5,4)(1,5,5)(1,5,6)

(1,6,5)

11 pair sets in each series

5 such series of (1,2,3,4,6)

5 already counted having 36 sets

Total cases =5×11 +36

Total cases = 91(new sample space)

Favourable cases = (4,4,5)(4,5,4)(5,4,4)

Prob = 3/91

hope this will help!! mark as brainlist!!!

Answer 2

Answer:

Mercury is the only one in liquid state at room temperature. It's used in thermometers because it has high coefficient of expansion. ... It also has a high boiling point which makes it very suitable to measure higher temperatures. Also, it has a shiny appearance and doesn't stick to the glass surface of glass.
