In a simultaneous throw of a pair of dice, find the probability of getting:a) 7 as a sum b) a doublet of odd number c) not a doubletd) an odd number on the first dicePlz give answer in steps

Answer»

Given : a simultaneous throw of a pair of dice

To find : the probability of getting

Solution:

a pair of dice thrown

total outcomes = 36

7 as sum

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

Probability of 7 as sum = 6/36 = 1/6

a DOUBLET of odd number

( 1, 1) , ( 3, 3) , ( 5 , 5)

probability of doublet of odd number = 3/36 = 1/12

not a doublet

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

Probability of not a doublet = 1 - 6/36 = 5/6

an odd number on the first dice

Probability = 3/6 = 1/2

5x^2=4x+7 quadratic equations by square method

Answer»

$\huge\underline{ \underline{ \bf{ \blue{ \: solution \: : = }}}}$

by USING QUADRATIC formula,

$\bf {\boxed{\frac{ -b + - \sqrt{ {b }^{2} - 4ac} }{2a}}}$

⠀⠀⠀⟹⠀ $x = \frac{ - ( - 4) + - \sqrt{ - 4 {}^{2} - 4 \times 5 \times ( - 7)} }{2 \times 5}$

⠀⠀⟹⠀⠀ $x = \frac{ - 4 + - \sqrt{16 - 4 \times 5( - 7)} }{10}$

⠀⠀⠀⠀⟹⠀⠀ $x = \frac{4 + - \sqrt{16 - 140} }{10}$

⠀⠀⠀⟹⠀⠀ $x = \frac{4 + - \sqrt{156} }{10}$

⠀⠀⠀⠀⟹⠀⠀ $x = \frac{4 + \times 2 \sqrt{39} }{10}$

⠀⠀⠀⠀⟹⠀⠀ $x = \frac{2 \sqrt{39} + 4 }{10}$

⠀⠀⠀⟹⠀⠀ ${\bf{\boxed{\pink{x = \frac{ \sqrt{39} + 2}{ 5}}}}}$

⠀⠀⠀⠀⟹⠀ $x = \frac{ - 4 - 2 \sqrt{39} }{10}$

⠀⠀⠀⠀⟹ ${\boxed{\pink{x = \frac{2 - \sqrt{39} }{5}}}}$
