Lanzar dos monedas ¿Cuál es la probabilidad de obtener como mínimo un sello?

a) 1/4

b) 2/4

c) 3/4

d) 4/4

you can't solve x because it is 2 linear equation and you only have one equation

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
