Question

Out of 1000 small colored bulbs 81³/² are of white color 5³ are red colored 2(power6) are green colored & rest are blue coloured. What's the probability that bulb chosen is:
1. blue coloured
2. red coloured
3. White coloured​

Answer 1

Answer:

please mark as brainlist

1. 41/500

2. 1/8

3. 729/1000

$no.of \: blue \: coloured \: bulbs$

$=( 1000 - ( {81}^{ \frac{3}{2} } + {5}^{3} + {2}^{6} ))$

$= 1000 - (729 + 125 + 64)$

$= 1000 - 918$

$= 82$

$Probability \: \: of \: \: blue \: \: bulb \:$

$= \frac{No.of \: blue \: bulbs}{ Total \: bulbs}$

$= \frac{82}{1000}$

Answer 2

Step-by-step explanation:

1. 41/500

2. 1/8

3. 729/1000

no.of \: blue \: coloured \: bulbsno.ofbluecolouredbulbs

=( 1000 - ( {81}^{ \frac{3}{2} } + {5}^{3} + {2}^{6} ))=(1000−(81

= 1000 - (729 + 125 + 64)=1000−(729+125+64)

= 1000 - 918=1000−918

= 82=82

Probability \: \: of \: \: blue \: \: bulb \:Probabilityofbluebulb

= \frac{No.of \: blue \: bulbs}{ Total \: bulbs}=

= \frac{82}{1000}=
