Given there are 50 students ,
so for probabitlity we do
favorable/total
a) opted a french= 12/50=0.24=24/100[if want solve]

b)doesn't japanease means except japanease
so 50-8=42
probability is 42/50=0.84=84/100 [ if want solve]
c) either sanskrit or geman means except sansrit and german
first we have to find german=?
so, 40-50=10
german = 10
now sanskrit+german+14+10=24
so given either sansrit or german so 24-50=26
probability=26/50=0.52=52/100[if want solve]
