Ответ:
P(tails )= 1/2
so Required probability = 1/3 * 1/2 = 1/6 answer
Ответ:
1/6
Step-by-step explanation:
Color of Shirt Number
Red 1
Blue 6
Green 1
Pink 4
Total shirts=1+6+1+4=12
P(Dennis picks a pink shirt)=no. of pink shirts/total no. of shirts
=4/12
=1/3
P(coin lands tail)=1/2
P(Dennis picks pink shirt and coin turns up tail)=
=1/6
(since, the events were independent P(A∩B)=P(A)×P(B))
Ответ:
3(2(l+w))= lw
6l+6w=lw
6l=lw-6w
w(l-6)=6l
w=6l/(l-6)
the smallest perimeter = 2( l+ 6l/(l-6))
