To solve the given expression, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). We will start by solving the innermost parentheses and work our way outwards.

Paso 1: Evaluar la expresión interna

Primero, evaluamos la expresión más interna: \[ -2 + 5 = 3 \]

Paso 2: Multiplicación

Luego, calculamos la multiplicación: \[ 4 \cdot 3 = 12 \]

Paso 3: Sumar dentro de los corchetes

A continuación, sumamos dentro de los corchetes: \[ 7 + 12 = 19 \]

Paso 4: Evaluar los corchetes exteriores

Ahora, evaluamos la expresión en los corchetes exteriores: \[ -3 - 19 = -22 \]

Paso 5: Sumar y restar los términos finales

Finalmente, sumamos y restamos los términos restantes: \[ -2 + (-22) - 4 = -28 \]

Respuesta Final

\(\boxed{-28}\)

Sometimes babies are born a little early. When this happens, skin sensors are used to monitor a baby's vital signs, such as temperature, pulse, and breathing rate. The trouble with skin sensors is they attach to the skin and can be uncomfortable. Researchers have developed a new system that doesn't make contact with the baby. Instead, it uses wireless cameras to monitor vital signs. Another issue with skin sensors is they're often inaccurate; a baby's slight movements can set them off. The cameras in the new system are highly sensitive, however. They detect the newborn's pulse by analyzing skin color, which changes slightly with every heartbeat. Even at night, babies need to be monitored. The new system deals with low light by using infrared cameras, which use heat instead of light to create images. Match the problems with their solutions. Skin sensors can be a source of discomfort. Small movements cause false alarms. Newborns must be monitored at night. The new system is contactless. The new system uses skin color to monitor pulse. The new system uses infrared cameras.

Among 6872 cases of pacemaker malfunctions, 318 were found to be caused by firmware, which is software programmed into the device. If the firmware is tested in 3 different pacemakers from a batch of 6872 and the entire batch is accepted if there are no failures, what is the probability that the firmware in the entire batch will be accepted? Is this procedure likely to result in the entire batch being accepted?
