Sia ? 6 years, 2 months ago

In {tex}\triangle {/tex}ABC, BD {tex} \bot {/tex} AC
{tex}\therefore {/tex} In right {tex}\triangle {/tex} ADB, BD² = AB²- AD² ...........(i)
In right {tex}\triangle {/tex} BDC, CD²=BC²-BD².............(ii)

Subtracting (ii) from (i) we get
BD² - CD²= AB²- AD²- BC²+ BD²
= AC²- AD²- BC²+ BD²
= (AD + CD)²- AD²- BC²+ BD²[AB = AC, Given]
=(CD²+ BD²) - BC² + 2AD.CD [AC = AD + CD]
= BC²- BC²+ AD.CD [CD²+BD² = BC²]
=2AD.CD Proved

Find the probability of 52 Mondays in a leap year

Posted by Yogesh Kumar 6 years, 2 months ago

CBSE > Class 10 > Mathematics

2 answers

Yogita Ingle 6 years, 2 months ago

1 year = 365 days
A leap year has 366 days
A year has 52 weeks. Hence there will be 52 Mondays for sure.
52 weeks = 52 x 7 = 364 days
366 – 364 =2 days
In a leap year there will be 52 Mondays and 2 days will be left.
These 2 days can be:
Sunday, Monday
Monday, Tuesday
Tuesday, Wednesday
Wednesday, Thursday
Thursday, Friday
Friday, Saturday
Saturday, Sunday
Of these total 7 outcomes, the favourable outcomes are 2.
Hence the probability of getting 53 Mondays in a leap year = 2/7.
